Personally, I thought JW2 was an appropriate upgrade from JW., as it expanded on the universe and felt appropriately bigger and better. The problem I had with JW3(which wasn't a big problem to be clear), is that it didn't really do much to up the ante, and felt a little samey to JW2. In JW2, you get a little more in depth with the network of assassins, and a side group goes after him. In JW3, it's pretty much the same deal, only it's the entire network...minus some sympathizers helping him out when it's convenient to the plot. The formula didn't evolve much, and was just an excuse to put Wick in some action scenes. I also think the series is missing a key antagonist. He had one in the original, and even the sequel to a lesser extent. In JW3, he's just fighting against the odds that some shadowy organization has put against him.
