Shockingly, I didn't feel the ridiculous length of John Wick 4 as much as I thought I would, but it could have been shorter. That is, many of the fight scenes just went on for too damn long and were very repetitive (in that often there were just more people coming at Wick in every situation). The best ones were the extended one-on-ones using the fight choreography the series is known for, but they were few and far between.
That said, I enjoyed it quite a bit. I loved all of the Paris stuff even if some of it had my eyes rolling vis-à-vis the geography. It wasn't as pretty as #3 (IMO, the best visuals) but the plot was somewhat better, though it still definitely suffers from the "trying to do too much" element that has plagued this series since #2. In my rewatch of the first three, #2 rose significantly in my esteem but not quite enough to topple #1, which will always have my heart for its simplicity of concept and creativity of execution.
