I've actually got this rented on my phone to watch this weekend. I'm pretty excited to watch it. I've heard only positive about it. Plus it's Tom Hanks starring; he's usually only in good movies (or at least the ones I've seen).
ETA: I just finished watching it, and I truly enjoyed it. I will say that I think it is for a certain audience. Clint Eastwood is obviously a fan of Sully and he really hammered in how calm the pilots were in the final 200-odd seconds of the flight. This movie isn't going to get your blood flowing (although I cried when the baby did...I can't help it. I have a baby), rather it's more for getting an interesting view of the event.
If you are looking for something action packed and filled with excitement, I'll direct you toward "Flight." (viewer discretion advised)
