Very, very underrated film, and in my opinion, this is one of Brian De Palma's finest films. It is great to see Robert DeNiro in his humble years, and this is certainly not an exception for me. His performance and the film itself is very natural, but still with artistic touch. The amateurish look of the film added to its humor, and the editing was good. The ending determined the fate of the three main characters, each having a semi-tragic feeling, but still be giving your face a weird smile as the credit rolls. I was very surprised by "Greetings" as a whole, I never thought it will be this good, because I just picked my copy of this in a "sale" bin, so thank god I've bought this unique film. The non-linear approach to the film made the film one-of-a-kind, filled with quick cuts and colorful title cards to separate the episodic scenes. The "peeping tom" scene was very unforgettable, one proof that Brian De Palma, even at a young age, can make a film that is both artistic and humorous. The satirical approach to hot issues at the time was hilarious, especially the one about the JFK assassination and how can it drive a normal person into paranoia. "Greetings" is literally a hidden gem, one that I really did not expect to be that good.
