I was flipping through the channels and saw this was on this afternoon. It is a very poorly done remake. Many of the lines were so poorly delivered that I got the impression that the actors new it wasn't going to be very good.
On the other hand, I highly recommend the original Jimmy Stewart version. It has all of the charm that this version lacks. Stewart's Dowd cannot help but be loved, while Anderson's Dowd feels wooden, and I ordinarily like Harry Anderson. When watching the original, you find yourself hoping that Harvey is real and you come to love him. In the remake, you find yourself not believing that any of the characters are real. They all come across as actors on a stage acting a part rather than actually being the characters. If you want to see Harvey, do yourself a favor and see the original. This version is not very good.
