In a way, I have to agree with him being that big. Remember, this is a comic book that started YEARS ago. At the time, 7' tall was HUGE. We now have basketball players who are 7 1/2 feet tall. Anything smaller than like 10' tall would have made him look tiny.
There were some things I didn't like but it was OK overall. Some of the transformation and fight scenes were pretty intense. And I like that it seemed like he wasnt used to his size or strength. Clumsy even.
I liked when they hacked him off and he grew like another 2 feet. Good baseline for a sequel.
