Star Wars:
Love Lucas's originals (1-6), 7 was disappointing and derivative but still fun, 8 brought it back to where it needs to be. The spin offs are good too, I thought Rogue One was amazing, and the new Solo, while not a necessary masterpiece or anything, was still a solid film that I'd want to watch again.
The Matrix:
The first one was a true masterpiece, with references that strike many of us even more so now that we've woken up to TTATT. Was not crazy about the two sequels. They were interesting and had some world building and neat cinematography, but dragged too much.
Men in Black:
Again, loved the first one. I hated the second one. To me it just seemed to be gratuitously aiming for shock value in the vein of the first but without earning it story wise. And the very fact that Tommy Lee Jones came out of retirement completely ruined the character arc from the first film, rendering it meaningless and undoing the first films perfect ending just for the sake of another outing. I like time travel, so I did enjoy number 3, and also thought the actor impersonating his younger version did a good job. But since it was built on the premise of number 2, which ruins number 1, that dampened my enjoyment. Also, I thought the ending was pretty convoluted and shoehorned, about him knowing Will Smith as a child, and it totally didn't mesh with the original.
