Better than hipster critics make it out to be
Mr Right is not trying to be deep, thoughtful, or any of that stuff.
It wants to entertain and be fun to watch and it achieves that. And it does a better job at that compared to brainless action flicks, like F&F, or Transformers, or any of those style over substance movies, that just fail on every level.
I would agree the movie had more potential, than it utilized, but it was fun to watch. Sam Rockwell and Anna Kendrick pretty much carry the movie, without both of them it wouldn't be nearly as entertaining, but it was.
So give it a try.
