Not posting any spoilers here, but if you were on the fence about going to see The Force Awakens, then I strongly suggest that you go see it.
If you have seen it already, there's a spoiler-heavy thread over in the EotE forum for discussing the film.
JJ Abrams gave us a worthy successor to the original films, with this film having much of the feel and especially charm of those films. The new heroes certainly pulled their weight and then some without being carbon-copies of the original heroes.
There were some significant plot twists that I saw coming, but that was due more to me being older and more learned of the tropes used in media than any direct fault of the movie.
