It's fun, but has an awkward first part, and it's unfortunate that good Lex loses his relevance, and that awkward romance between J'onn and Rose...
Thinking of it, sudden, awkward romance may be a problem with DCAU (Since the movie was supposed to be part of it and had most of its script unchanged), 'cause Supergirl immediately fell in love with Brainiac 5, despite them knowing each other for less than an hour... And I remember that in the episode that introduces Catwoman, Bruce seems like he falls in love with her after a single date, wonder if there are more cases besides those, but, 3 times is already pretty noticeable lol..
