It was OK if you keep your expectations in check. It was entertaining enough for what it was.
I'm in with what others have said, which is probably most people.
Matrix. It was awesome. One of the best ever. One of my favorite movies ever. Just so goddam great, and still is. Have watched many times. And will watch it again.
Matrix 2. Simply put, the most excited I ever was, ever, to go see a movie sequel. I went to see it at the Thursday late night showing on launch weekend, the first available show. It was kind of a letdown. Having watched it many times since, its not all that horrible, it has some cool stuff. But, it just seemed they didn't carry the concept forward the best way they could have. The mystery was gone.
Matrix 3. Saw it at Imax. It was kinda terrible. Again after watching it, its not too bad, especially if you could cut out about the entire 30 minutes or so where they were in the city having a party or whatever. The ending was overblown and not too original. The trilogy was done, OK we get it, but in the end, the original movie was the real shit.
Matrix 4. Its just what it is. I sure as heck wasn't expecting much, given their track record since the Matrix films. It was a good popcorn night. Just don't expect anything great. It was at least a bit more entertaining than any recent Marvel movie I have seen, such as Endgame. I would rate it better as a callback than that Star Wars 7 movie.
Its just a matter of how you want to contain the world!
Do you say, there was Alien. And then there was Aliens. And that's it, there were no more Alien movies after that. I do believe so.
Do you say there was Terminator, then there was Terminator 2, and no more Terminator movies after that? It would be reasonable. But I kind of liked T3, and T4 too. Even Genisys was OK by me. Terminator movies, they are cool, I'm a sucker for them. But man, they managed to put a knife in its back with the last one Dark Fate. They did it, they terminated the franchise.
Do you say, there were just 3 Star Wars movies? Yes, yes, I think so, in my world. 1-2-3 were horrible atrocities since day one, and 7-8-9 were not as bad, but just, not good.
