Yeah -- the werewolf, the dementors and the shrunken heads -- I didnt like them.. I mean the CGI was not impressive at all.

The dementors were too thin and didnt look very scary -- but I guess that's intentional coz the production is constrained to make them not too scary in order to pass the PG 13 rating.

And the shrunken heads were just simply ANNOYING! I didnt find them funny at all..
