Very true that the more you know about a character's origins, the more distracting these movies can be. Catwoman was bad in so many ways, but I couldn't get over how they just made up a mystical origin story for her out of whole cloth.
I don't feel that movie needs to stick to the comics 100%, but a little respect for the canon goes a long way for me. Luckily I don't know a ton about Wonder Woman's origins, and what I do know mostly lines up with what I've read from the reviews (she lives on an island with Amazon goddesses with Greek names ;))!
Finally, my wife hates hates hates super hero movies, so when she said she wanted to see wonder woman, I frankly don't care if it's worse than the fantastic four - I'm going to enjoy the crap out of it!
If your wife is into it, you should 100% go. I bet she is going to enjoy it.
I think I am just too much of a geek for this one. (I should have included that in the title).
If you see it, please come back and let me know what you thought. So many of these comments have really helped me to better understand my issues with the movie. If I were going to write a review today, it would be very different. I would have definitely written it from 2 different perspectives: from super geek point of view it was little boring because I knew too much already. From a more casual fan's point of view, I bet it is more enjoyable.
