Iron Man 2 CelebCam - Robert Downey Jr.
RDJ previously admitted to The LA Times that Iron Man 2 was dissatisfying and disappointing. After Marvel began establishing its shared cinematic universe with Iron Man, something went wrong with the sequel. While we don't want to put words in their mouth, the film seemed like a lazy attempt, which seems to be what RDJ is getting at. The mindset seemed to be that no matter the content, the film would do well because it's part of the Iron Man franchise. They were right to some extent, as Iron Man 2 took the top spot at the box office two weeks in a row. However, it didn't exceed expectations and the film as a whole is widely thought of as the weakest link in the MCU chain.
