According to their latest primetime listings, the CW is going to re-air the popular Elseworlds crossover event on January 7th and 8th...Elseworlds had great ratings and was considered a success so it’s a solid idea to bring it back for an encore presentation.
In case you missed anything, didn't see it the first time, or want to enjoy it again...you've got a second chance to start 2019.
Happy New Year!
