I'm keen to see if Ballerina is going to be a good spin-off, buuut not super on board with another John Wick ... the story had a good end, and it would be nice to just leave it on a high.
I recently did a marathon of the four films, and TBH after the first one it really did feel like a marathon. I got up and made drinks during some of the fights and didn't feel like I'd missed anything.
The part with Halle Berry was good, the final big set piece up the cathedral steps was great, and the final ending excellent, but I don't think I'm going to re-watch any other part again.
Star Trek Spoiler
See Picard series 2 for that
