I must say that I was very disappointed.
Crispin Glover is an excellent actor, and there were a few moments of true excellence, in particular the demise of the cat and the amazing visual when Willard emerges from the elevator.
But, overall, it was just way too predictable.
Willard did everything I thought he would, and nothing I didn't expect.
The scenes towards the beginning with the bosses shiny, new car and then Willard teaching the rats to tear up old tires in his garage was none too subtle in its forshadowing of Willard's first use of his new-found power. And of course one could predict from the beginning that he would take the ultimate revenge on his "evil" boss (Did anyone else think that Willard probably deserved his bosses tirades? I mean he was late to workevery fucking day).
I wouldn't have had a problem with predicting these scenes, as they seemed fairly essential to the story.
My problem is that these are the only things that Willard uses the rats for.
He could have robbed a bank, discovered his father's dirty secret, kept the big bad lawyer away.... anything that might have surprised me.
Maybe I would have enjoyed it more if I found rats to be creepy, but as it is I'm actually rather fond of rats.
