I didn't find the effects laughable - I thought they were quite evocative in the context of the story - but they definitely had a regrettably cartoonish quality

I wasn't talking about the CGI fairies, actually - I agree that they were decent enough. What was laughable were the practical effects - the wind and rain and the petals pouring out of peoples' mouths. In none of these cases did I believe that the characters were in actual danger (Estelle in particular seemed to just lie down and die, not drown).
