If you've never watched a show, you wouldn't know.
Reading a short summary on the premise and subject matter of the CW shows on IMDB is enough for me to know.
For whatever reason I can enjoy watching superhero/comic book movies but for tv shows I just don't have an interest.
I think you might be missing out, PM. The TV series have a lot more time to do character development and back stories, etc. Arrow, Flash, Daredevil and Agents of Shield have all been pretty entertaining, IMO, and have all spent time on fleshing out things more than a movie could.
I can certainly understand not wanting to watch such a show one week at a time. But with entire seasons available for binge watching, you can forego the wait in between episodes.
