Hey, who's the guy with the Hat? Is that a M-16 he's carrying? So, we have Manchester Black, Menagerie and the Hat! Omit Supergirl and you have Alice in Wonderland.

From the distinctive round drum magazine, I think it's a Thompson submachine gun, aka "Tommy gun."

Models of the era were fully automatic; it had a high rate of fire and was
nonetheless pretty accurate. Very dangerous weapon. And unless upgraded significantly or firing customized ammunition, completely useless against Kryptonians.

It fits the 1920-30's gangster style of the character. I think he looks great!

I was joking when asked if it was a M-16. It's looks like Machine Gun Kelly's peacemaker. I wonder if he can use his hat as a weapon like the guy in Gold Finger. That's the first thing I thought of when seeing this guy.

"As a physics teacher I love this show."

Me, too! (I'm also a physics - and chemistry - teacher.)

"Basically, Superman was originally just stronger (could run faster and jump higher, etc) than an average human. In the Golden Age of comics this was perfect. In the 50's and 60's he became so "over powered" it became ridiculous for the writers to find a villain that could match him. Same with Supergirl."

Well, the original Golden Age Superman was really *much* stronger (and more damage-resistant) than an average human. He could easily lift a car over his head and "leap tall buildings in a single bound". Bullets bounced off him, and it was said that "only a bursting shell could penetrate his skin". (A few years later, Superman could also fly.) With the advent of the Atomic Age and the Space Age, DC Comics seemed to try to make Superman more of a sci-fi publication. So instead of fighting gangsters and mob bosses, he was flying from one planet to another and battling aliens, and his powers increased enormously. In the Silver Age, Superman (and beginning in 1959, Supergirl) were only vulnerable to kryptonite (which apparently came in wide assortment of colors!) , "magic", and alien "super-science".
The Supergirl TV show has apparently attempted to place Kara's powers and abilities somewhere between those of the Golden and Silver Age Superman (though they have been very inconsistent in doing so). For instance, a "bursting shell" (or missile warhead) can't penetrate her skin, but it can put her out of commission momentarily (just a temporary setback). She can't push planets around, but can lift at least 10 tons with no problem. But she can't fly in space, because she needs air to breathe. (Loud, high-pitched sound seems to cause her distress, too.)
As some of you may already be aware, I've written a number of Supergirl fan-fiction screenplays in which I've tried to keep consistently to this power level.

As a physics teacher I love this show, and so does my daughter, and may I suggest a book; "The Physics of Superheroes" by James Kakalios ... I think this show does a good job of what "Smallville" did with Superman. Basically, Superman was originally just stronger (could run faster and jump higher, etc) than an average human. In the Golden Age of comics this was perfect. In the 50's and 60's he became so "over powered" it became ridiculous for the writers to find a villain that could match him. Same with Supergirl. Her (and Clark's) real strength came from their moral compass and from building teams and friendships. I don't WANT to see a Supergirl that simply shows up and kicks butt every week and saves the day. It's great (and, more in line with her original character) to get into trouble and use her wit and friends to get her out. Kara finding herself in, over-her-head, each week is great because if she was as overpowered as the Silver-aged comics Superman, this show would get predictable and stale after three weeks. I'd much rather see her against antagonists that matched her strength, but that she overcame through her morals and her reason. This show nails it! Thanks

Yikes you must really hate Arrow and The Flash then . They are barely featured anymore. And the others are actually doing the superheroing for them
At least the TITLE CHARACTER here on Supergirl has the most screentime still.

Yeah, I have some serious issues with those as well, but we aren't on TheFlash.tv. ☺

My complaint isn't simply a matter of screentime. Kara had plenty. She was fun to watch, too. Then she put the cape on and wow, it was like she had eaten a big bowl of failure for breakfast.

Maybe the Super Friends can take turns rescuing the title character. That would be great...
