opera ( the u. s. title be terror at the opera ) be somewhat of a letdown after some of dario other movie like phenomenon and tenebre and and suspiria . ( i still can not find inferno anywhere . ) it one of those movie that have a great first half but midway through it like someone start slowly let the air out of the screenplay and logic . the basic plot involve a beautiful opera singer who be be stalk by a deranged obsess fan . this killer begin kill people close to her in a most unique fashion . he bind and gag her and tape tiny sharp pin under her eyelid so if she try to close her eye she will gouge out her eye . this force her to watch while the killer murder her acquaintance in typically brutal and gory argento fashion . unfortunately and about midway through the film become sluggish and illogical . ( this be especially directed towards the killer motivation . i still haven not completely figure out why he such a nut . ) the end especially come out of left field in the bad possible sense . but and for about the first hour or so this be some of dario best filmmaking and the camera work be breathtaking . too bad it couldn not maintain it through to the end . rating represent7 .
