For a remake of a classic horror film, this is pretty well done. But, while I enjoyed it, there's no doubt that it definitely lacks a certain charm that the original films had.
And with the exception of having some ridiculous horror cliches throughout the movie, there aren't very many disappointing aspects. It really captures that classic horror feel that was present in the originals.
If you're a fan of the Evil Dead films at all, definitely give this one a shot. Even though it's a tad underwhelming, it's still a very welcome addition to the series.
