I don't really have a problem with Keanu lookin like John Wick.
Before Wick came out in the trailers they had Keanu saying, "Yea I'm thinking I' m back". That was basically them getting across in the advertising that Keanu was in some flops lately but he's back to that Matrix shyt you liked from before.
In the trailer for the second movie they had Fishbaurne nodding about them being together in the Matrix. Without the Wick franchise I don't think this movie gets made and they probably left the look the same as a thank you for giving them another chance closing out the franchise. I just hope they do it right.
