So far the best
There haven't been a lot of great female centric superhero movies yet. We've only had the '74 TV movie Wonder Woman, 2004's Catwoman, Elektra and of course this one. They've all failed which is why I think there haven't been many.
However I just watched the director's cut and while this film is heavily flawed with some terrible cringe worthy dialogue and plot holes, it's still a very fun movie with a likable heroine and side characters and a fun hammy villain in Faye Dunawaye's Selena. It has a nice fantasy, almost fairy tale type of atmosphere mixed with the comic book world. I also think it had great special effects for the time and it deepened the Superman world by showing us the inside of the Phantom Zone. It's too bad it failed so that we never got to see a sequel or Supergirl teaming up with her cousin in a Superman film, but I'm glad it lead to future work for Helen Slater being in Smallville and the Supergirl television series.
While next year's Wonder Woman looks quite epic and I believe Gal Gadot will do a fantastic job in the spotlight, this is the only decent female centric superhero movie right now and I think a lot of people should give it another look. Perhaps a bluray that includes a newly restored director's cut would help.
