I liked it except for the bad CGI at the end.

Totally agree. I suppose budget limited their effects, but the CGI was cartoon-like. I still liked the movie a lot, though - I just had to suspend my disbelief with regards to the effects.

Holland doesn't like Piggy Lookadoo.

I agree with both points made here so far. It was definitely different, which is what the horror film genre is lacking lately.
