After M.2 and M.3 I fell in love with Matrix again.
At the beginning it is a fast resume of M1 and the rest, so for a new viewer gives a quick intro.
At some points it could feel like all the new Star Wars movies: You see the same story again, but with new characters and new technology, but basically is the same [in fact, I think there is a dialogue in M4 referring to that]. But later on it developes as a new nice story, kind of the proper ending that M3 did not gave us.
I totally recommend to watch it.
