This is going to sound ridiculous, because they are wildly different, but my thoughts on Game Night are similar to my thoughts on American Hustle. Are they perfect movies with pristine plots? Maybe not, but between the great performances, humor, and relentless fun energy of the films, they're so easy to get caught up in.
Game Night lived up to the rumors I'd heard about its humor, but exceeded my expectations in both creativity of the plot and technical elements. The jokes pretty much all land, as the script is great. never overplaying or repeating the same jokes but relying on strong chemistry between actors and clever lines to deliver humor. I thought the plot was simple and obvious - Brooks set the whole thing up, duh - but the twist with how the whole night actually happened and what the situation with Brooks really was was super smart. Yes, the plot goes into some wild directions, from the accidental gunshot to the crazy hot potato with the egg to the climactic plane fight, but it never goes off the rails completely. McAdams is really phenomenal in the lead and frankly one of the best performances of 2018 for me, and the whole ensemble is effective (though Ryan could've been a little less stupid). The peripherals were all very good - a good score, very creative cinematography, and lots of small touches and details, down to a hilarious end credits scene. Even the romance was well done, with what felt like a real relationship and nice scenes with a bunch of fast takes. Comedies never get a lot of respect, and there have been few really good ones lately, so the ones that are genuinely funny and also work from a filmmaking perspective deserve to be considered great movies period, and Game Night is one of them.
