To be fair about the Wonder Woman movie. It's already well known the people at DC themselves have no say in their movies and those executives at Warner Brothers have all the say. They don't have any faith in in a Wonder Woman movie, female-led movies or DC properties outside of the big two sadly. They also don't seem to have any respect for the source material, which doesn't help things.
In short DC will never the same success as Marvel on the big screen, as long as WB doesn't have more faith in the DC properties they own.
I think the fact they registered domains for Shazam, Wonder Woman and Aquaman in 2000 and did nothing with them for years, shows how much they actually care about their non Batman / Superman properties.
I'm not gonna get super excited, though an Aquaman could be badass, but I expect it to be "meh" currently.
I liked it. Thought that Peter and Gwen had great chemistry (I'll admit the ending did get to me, but I expected it). Peter's character arc was well done. I thought Electro was alright, and I thought that Harry as The Green Goblin was done well, even if Norman Osbourne was wasted (thankfully he'll appear in the sequels).
I do agree though, that the film was a little overcrowded. Sony was obliviously trying to push all those characters in there so they promote the proposed Sinister Six movie that their trying to make. Also the film was CGI overkill, something that I'm not a fan of.
The real problem with a Wonder Woman movie is the general stereotype that female superhero films don't sell (although their has yet to be a good female superhero film), that and the fact that WB seems too lazy to go out of their Batman / Superman confort zone anymore.
