John Wick 1 was the best imo. The story was somewhat coherent and drew attention. There was plenty of action that was exciting without being over-the-top ridiculous.

Next up in John Wick 2, the story was still somewhat coherent and though some scenes started to become a bit nonsensical(tons of assassins and no police etc), it was still a solid movie and easy to follow.

In John Wick 3 everything took a nosedive into utter nonsense. Part 4 expanded on this with nothing but lots of ridiculous wild nonstop fights. Typical Hollywood cash grabs devolved into absolute boring and ridiculous rubbish.
