I agree with almost everyone who has voiced their likes/don't like opinions of this show, and because they were very well expressed by everyone who has contributed so far, I won't repeat any of them here. However, I have had a few other completely different gripes about the show that haven't been mentioned by anyone else so, for whatever they may be worth, here they are.
I like continuity in anything, simply because it means that someone got their facts straight to begin with, and cares enough to keep them straight afterwards. But one really big beef that I have is the perpetual inconsistencies that have permeated this show for many things, such as dates and time-lines:
* In 2015, Kara was 24 years old; when added to the 24 years that her pod was stuck in the Phantom Zone, this would have made her year of birth (on Krypton) as 1967, and if she was 12-13 years old when Krypton was destroyed, then that would therefore have been in 1979 or 1980, and she would have finally arrived on Earth in 2003 or 2004. And in Feb-2017, in Episode 2.11, "The Martian Chronicles", Kara said that she was looking forward to celebrating her "13th Earth birthday", thus making her arrival on Earth as Feb-2004.
* And yet, if Jeremiah Danvers was recruited into the DEO a few months later (as per Eliza's description in Episode 1.05, "Livewire"
, and Jeremiah was then reported killed in Peru the following year, then this would have been in 2005. But in Episode 2.07 ("The Darkest Place"
in 2016, Jeremiah told Kara that he'd been a prisoner at Cadmus "for 15 years", which would have been since 2001, 3 years before Kara even arrived on Earth.
* In another episode later that same year, J'onn J'onzz talked about how he'd "worn the face of a black man for 15 years", which would also put that meeting in Peru a few years before Kara's arrival on Earth.
* And in Episode 3.01 ("Girl of Steel"
in 2017, Supergirl told J'onn that she'd been Kara Danvers "for 15 years", thus putting her on Earth in 2002, two years before she actually arrived.
* At the end of Episode 2.22 in 2017, we see the witches on Krypton putting the baby future-Reign into a pod to send her to Earth, and are told that this was "35 years ago" which, by all of the other time-lines, would have made it 2-3 years after Krypton exploded.
* We were frequently led to believe that Cat Grant was still working at The Daily Planet when Clark Kent and Lois Lane were also there. But in Episode 1.08 ("Hostile Takeover"
in 2015, Cat tells Kara that she had her first son, Adam Foster, 24 years ago, AFTER SHE'D LEFT THE PLANET to start CatCo; so this would have been in 1991. If Kal-El arrived on Earth in 1979-80, and grew up as Clark Kent, than he would have been only about 11-12 years old when Cat left The Planet to form CatCo; so how could Cat have worked with either Clark or Lois, who would presumably be no older than Clark is?
Dates and times aren't the only things that this show isn't consistent or logical with:
* And if the DEO was first formed to deal with any potential threats that Superman presented in Metropolis, then why was it located in National City in California years before Kara even arrived on Earth?
* During the "Crisis on Earth-X", Harrison Wells said that there are 52 multiverses, with 52 Earths, but in the "Elseworlds" cross-over, the Jay Garrick/Flash was from Earth-90.
* The Luthor mansion would have to have been located outside Metropolis (again, east coast) because that's where Lex-Corp was located, and where Lex and Superman opposed each other. And yet, last year, Alex was able to easily drive from National City to the mansion on her motorcycle. And just recently, Lena was able to travel back and forth between the mansion (where a dying Lex was) and the hospital where James was, in no time at all. And when Manchester Black caused the power disruption, National City and the mansion were both affected by that. And yet, when Lex and Otis were making their getaway in the helicopter, Supergirl stopped them, and Lex escaped by using a flying device to zip down to Metropolis right below them. Now, the Luthors may have been able to afford the largest mansion in the world, but I doubt that it was so big that one end of it is on the east coast, and the other end of it is on the west coast. Hmmmm?
There are many other date/time/place inconsistencies that I've noticed, but for the sake of space these examples will do.
Another thing that bothers me is how they always seem to be trying to make Supergirl way less super.
* Flying speed: In Episode 1.20 ("Better Angels"
, she carried Fort Rozz up into space and pushed it away from the Earth, and this would have required her to fly at considerably better than 'escape velocity', which is approximately 40,300 km/h. And in the conclusion of "Elseworlds", Supergirl and The Flash traveled around the Earth in opposite directions, depicted on-screen as taking her only a mere second. The circumference of the Earth is 40,000 km, so she would have been flying at 40,000 km/SECOND!
And yet, how many times have we seen her desperately struggling to catch up with a rocket or missile that's traveling at only Mach 1 or 2?
* And how about her strength? In Episode 1.15 ("Solitude"
, James says that the weight of the key for the Fortress of Solitude is "a million tons of dwarf star"; and in Episode 4.14 ("Stand and Deliver"
, The Hat says that the key to The Fortress weighs "500,000 kg", which is 500 metric tonnes (a lot less than a million - another inconsistency). And let's not overlook the fact that in 3.01 ("Girl of Steel"
, Supergirl lifted up a nuclear submarine, which would have weighed at least 10,000 tonnes; and also that, according to General Lane in Episode 1.20, Fort Rozz weighed "a million tons".
The reason for mentioning all of these is that, for all of the obvious super-strength that she is supposed to have, I have lost track of how many times Supergirl doesn't seem to have the strength necessary to punch out almost anyone who she's facing off against, whether it's another alien, or a meta-human, or a human assisted by some device of some kind. Indeed, it seems as if almost everybody lately has some kind of device to render Supergirl helpless, not to mention what Menagerie's snakes did to her.
So, if it seems as if they really don't want her to be so super, then what's the point of having a show about "Supergirl"?
I know that it's only a fantasy-superhero TV show, and maybe I'm the only one who notices these kinds of inconsistencies, but it has me wondering why the writers/producers are so careless - or maybe just indifferent - about keeping their facts and backstories straight, or about letting Supergirl live up to her name.
