Noah Antwiller from the Spoony Experiment made a great review of it with his brother.
I think he made some great points. He wound up hating it a lot more than I did, but a lot of the stuff he said made a lot of sense too:
The acting aside from Worthington and Weaver really is kind of hammy;
Most the characters (villains) are somewhat cartoonish (although that Colonel made me laugh out loud when he pulled that giant knife from the mech, and the scene of him drinking his coffee while everyone is being blown to hell was simply priceless);
The movie is way too long.
It's worth to see it just for the spectacle, but don't expect it to change your life or anything.
