It's brutal, violent, bloody, gruesome. I don't know what the critics are thinking, but this remake doesn't need humor. Humor will not fit in with the tone of this movie and it's the best horror movie remake yet, however I did find a few parts a bit goofy, such as how Eric says "Oh my god, why the f**k would you do that?". Practical effects were incredible. Jane Levy was scary and awesome. Shiloh Fernandez was great and Lou Taylor Pucci was good. I don't give a damn about the other two girls, which is the only problem with this movie, the acting was good but not great. Mainly because there's no character development in this movie, besides Mia and David. I expected more because the trailer showed too much. Best horror movie of the year.
J.J Abrams did what he is best at: gives us a good mystery, even if it has to do with monsters. Yes, I know, he's the producer. Very enjoyable (and slightly scary).
