Maybe I was just not in the mood for a brainless movie, or maybe the movie was significantly less interesting than average movies, but I just didn't like it. It had no substance. No interesting characters. No interesting plot. It was just scene 1, scene 2, scene 3 etc etc without anything really make me care or even want to know what will happen next. It was... boring. Now honestly, despite being a big comic fan, I never particularly cared for Iron Man as a character. I found him uninspired and prototypical. He wasn't bad, but he was always boring in comics, and now in movie. I definitely enjoyed the 1st Iron Man more than the 3rd but the 2nd and 3rd were snore fests and all the tech and actions didn't help one bit which is a double whammy because I am also a huge sci-fi fan on top of loving comics but I just couldn't enjoy this movie. Again I cant put my finger on it, but something was just off. It was not fun.
