I remember being disappointed with it. There was a lot of positive buzz on the movie when it first came out and I guess that tainted my view on the movie. From all the good things I've heard I should probably watch it again.
On another note, the twins were also involved heavily in the movie Northfork. It's similar in style but just like TFI, it evokes emotion from viewers but it never really comes together. I personally thought Northfork would at least garner some kind of following but that never materialize. It has all the elements in place, but the pacing probably turned a lot of people off.
