Saw this last night and was pleasantly surprised. A very entertaining film with fun, bloody horror and some great characters. The story felt a bit rushed at times to me, but the pacing was mostly excellent (it builds nicely while gradually becoming more and more chaotic).
And the CGI was pretty good for the most part. Couple of dodgy blood effects here and there but that was about it. The facial transformations in particular were rather impressive.
I still
think I prefer the original, but this is
by far the best recent horror remake I've seen.
