I watched this weekend and it was better than I expected (I had very low expectations). I'm not a big believer in the 'too soon' mentality. This was an event that happened, and there's no reason to hide from it. I know some of the survivors weren't happy about the movie, but others were heavily involved in the production. My only complaint is that there was too much about Tommy Saunders' (the composite character) background/history considering he wasn't a real person so the background is fiction wedged into the middle of a true crime film.
My friend was injured by the 2nd bomb. I talked to her after I watched the movie on Saturday to see what she thought. She didn't really have strong feelings either way. She did mention that it was strange that they seemed to focus only on two of the survivors. She told me, "it was an alright movie, but it's Mark Wahlburg's interpretation of what happened shown through Peter Berg's lens." Her point being that the movie couldn't focus on everything, and that they couldn't make everyone happy. I thought it was a great point.
I'm looking forward to the Jeff Bauman movie; his book was great, so I have high hopes for the film adaptation. Jeff was very involved with the production, so I expect that it will be very respectful towards everyone involved.
