The movie was great and the script was enjoyable, but I found that it had a lot of errors that could have been corrected by proofreading. This seems very odd. Thank god for the people who look this stuff over, that's all I can say.
...but, as a previous poster mentions, this version is subtly different to the film -- the film's version is better as elements are explained more carefully and Goodspeed's character is more likeable. Hummel's character is also broadened in the film version. Anyway, good fun!
