Depends what you mean by "better". The sequels lean waaay more into the whole Assassin World thing. So if you wanted a lot more about the gold coins and Hitman Hotel and whatever shady organization apparently runs the whole world on that basis, the sequels may be for you.

But no, if you didn't care what happens to John Wick at the end of the first movie, you'll probably not care what happens to him in the second and third movies.

TBH I thought the premise of the second movie was solid, but all that High Table bullshit needed to be thrown in the trash where it belongs.
