I expected to really enjoy 'Saturday Night'. I was hoping for a fast-paced and hilarious look at a historic night. They got the fast-paced bit down (perhaps even a little too fast-paced for its own good at times) but the hilarity never came. Instead the movie came across quite unpleasant, with forced drama for the most part.
There are a lot of characters in this movie and very few of them are interesting to watch. 1975 was far too long ago for most of us to know who these people are, but it seems like the movie just assumes that we will. And because of the structure there isn't much, if any, time to set up and develop the characters. So we are just told, here's a person who was there that night, enjoy their screen-time. I will say the scenes with Chevy Chase were interesting, but that probably worked for me because I know who he is and am a big fan.
I felt like there was so much potential for comedy and witty dialogue and yet it just never came. A funny situation would arise with a character taking drugs that were too powerful for them, but the movie was in such a hurry to get to the next scene that it couldn't breathe and become a memorable scene.
This probably sounds like a very negative review, and it is, but it's more negativity aimed at what this film could've and should've been, as opposed to the general quality of the film. It isn't a bad film, but it should have been so much more. 6/10.
