Saw it yesterday. They changed A LOT of things. The Credits kinda tip you off to that. Hancock and Amini both got writing credits along with Daugherty, who also got a "Screen Story" credit. The result was a mess. Definitely a step down imo.
I am in the same boat ... I loved the Huntsman backstory and arc better in the original... I think this movie was blah/boring... and Rotten Tomatoes agrees... 46% rating
