The Incredible Hulk (2008)
I didn't start watching MCU, or any other Marvel movies, until Guardians of the Galaxy. After that, I got caught up with Thor, Captain America, and The Avengers as new installments of each came out. Up until this month, this one and the Iron Man movies were the only MCU movies I hadn't seen. A few weeks ago, I watched the first Iron Man movie (loved it!). Now, I watched The Incredible Hulk.
Surprisingly good. At the time it was released (and when the previous version was released five years earlier), I couldn't figure out what the appeal was of a raging giant green guy. I understand now, and maybe the Avenger movies warmed me up to it, that the story revolved around Bruce Banner trying to control himself and General Ross trying to contain/cover up his experiment. I also liked the Captain America connection.
