Just saw it this afternoon. There were only 6 other people in the theater -- my favorite way to watch movies.
I loved it more than I thought I would. I was worried the video I posted earlier would spoil too much, but it didn't. More of the assassin underworld/universe is exposed, with new characters, and beset by bureaucratic infighting that is present in every business/office setting. It was funny.
There is a lot of subtle comedy in this movie.
I understand the comments from others about the drawn-out fight scenes. That is probably my only complaint as well, but for a different reason. There was enough action in those scenes to keep me entertained, but it seemed "unrealistic" for John to have super-human stamina to fight so many different people for those durations. Sure, he's a very skilled fighter and assassin, and better than anyone else, but...oh well. it's a movie.
But I still very much enjoyed those scenes. There was enough differences in action, gore, comedy, etc. to keep me entertained. Several times I actually put aside the context of the movie, and just admired the craft of the actors and stuntmen. The months of training and coordination choreography that must have been needed to make them happen was quite impressive to imagine. They took their jobs seriously. The finished product on screen was fantastic.
The first knife-throwing scene was hilarious. Both John and his opponent had expended their supply of bullets, and they both did simultaneous double-takes when they realized they were in a museum surrounded by artifacts of ancient knives and swords. That extended fight scene was comically entertaining, and ended with some excellent gore. I audibly let out an "OH!" and shifted in my seat a little.
The presence of Fishburne and Reeves on screen together in Chapter 2 of course reminded everyone of The Matrix. And the nod to The Matrix in this movie was an unexpected gift.
"What do you need?"
"Guns. Lots of guns."
Some unexpected plot twists, and overall a great movie IMO. Looking forward to Chapter 4, expected out in May 2021
