I just watched Spiderman 3- what a ham-fisted, amateurish job by the writers and director! In this overstuffed installment, Spidey takes on 3, count em, 3 villians: Hobgoblin (Peter Parker's former best friend Harry Osborne, now bent on exacting revenge on Spiderman for his believed role in Harry's father's death), The Sandman (who, in a bit of revisionist hooey, is revealed to be responsible for the death of Peter's beloved uncle Ben), and Venom.
The only thing worth watching in this film are the special effects, which are incredible. The metamorphosis of The Sandman is thoroughly engrossing, as is the initial fight scene with Hobgoblin. The rest of the film, however, is a scatterbrained mess. The Peter Parker/Mary Jane romantic storyline has grown stale, and an ill-advised attempt to create a Peter/Mary Jane/Harry and a Peter/Mary Jane/Gwen Stacy love triangle (rectangle, quadrangle?) falls flat.
Then there is the puzzling montage where Parker tries to turn pimp daddy...wha? The supposedly poignant scenes are unintentionally comic, the plot points are telegraphed, and the acting is just plain rotten throughout much of this way too long film. Most egregiously, the storylines established over the decades-long history of the Spiderman comic series have been largely jettisoned in favor of the grossly condensed and distorted versions offered by the screenwriters.
Save your money. Read the comics instead.
