This movie got hyped past the moon when it came out, so my first viewing in 2009 was a huge let-down. Over a decade removed from its release, The Hangover is a fun, stupid comedy that you wouldn't be able to make today. 90% of the humor is pure shock value, "Wait, what? moments with 10% being actual structured jokes. It did get a lot of chuckles, but most are things that won't hold up on a re-watch. I had over ten years between viewings, so everything old was new again. If I watched it again tonight, there really aren't a bunch of moments that are going to be funny again so soon. The story is simple and the movie really doesn't have anything to say, so it's pure comedy and there just isn't as many actual comedic elements as Airplane or even Old School. The acting is fine, although we get more caricatures than characters. I will note that although it definitely didn't bother me at all, depending on how much you enjoy recreational outrage, there are a few jokes an gags that aren't 2020 PC approved. A comedy movie really has to either have something bigger or deeper to say or be packed with humor and The Hangover isn't either. It's an enjoyable, fast-paced dude-bro comedy, but it's not something that I can see watching again before another couple of years go by and I forget everything again.
