It's disappointing, especially after the amazing trailers. This movie is sooo cliched and cheesy, with plot lines that reads like a fanfiction, a bad one at that.
Barbara is nothing more than a geeky, nerdy, glasses wearing, awkward girl trope, that stumbles on everything, and drops whatever she's carrying. She then transforms into a confident and powerful woman, but how does the movie show this? By removing her glasses, and that she magically can walk in high heels now, because magic.
Maxwell Lord is also a weird vilain, with a weak motivation. That last scene with his son is laughable.
The only saving grace is Gal Gadot, but not even Wonder Woman can save this movie for me. First one is miles better.
