I don't understand people

Rating: 8/10 (13 January 2016)

I really do not understand why so many people hate this film. It is not just the critics (rotten tomatoes has it at 60%), but the users' reviews I've seen come down to 1s and 2s out of 10.
It is not a perfect movie, and certainly not the best David O. Russell film, but it still is extremely entertaining and well made. I really love Jennifer Lawrence's performance (I think that with her alone this film deserves at least an 8) and the rest of the cast is good too.
I see some people complaining about lack of plot, but I really didn't need it. One of the most loved movies of 2015, Mad Max: Fury Road is also short on plot, but when you have such good directors as Miller and Russell I don't see the problem.
I knew nothing about Joy Mangano before watching this, so I wouldn't know if the "based on a real story" thing is just bullshit, but if it is I don't care. This was a fun, well-crafted, inspiring and emotional film-experience and I feel like some people should cut it some slack. I don't hear much people saying it is "the best" or "perfect", so I don't get why would you go so hard on the film.
