Loved Suspiria, but I didn't care much for this second installment in the Three Mothers trilogy. Inferno is pleasingly stylized, but not in the same manner as Suspiria; though the gore is definitely ramped up in comparison. And, sadly, Goblin is missing from the musical score--a major let down. On its own (i.e. without comparison to Suspiria), the movie just doesn't do it for me. As soon as a scene has my attention it fades into a quirky, below average story, with tidbits seemingly thrown in for good measure.
Hopefully Mother of Tears will be better.
