Undies , It's probably better if you don't Google it. The link redirects you to movies Night of Giving Head & Return of Giving Head.
Superman 2 (out of the ones with Christopher Reeve of course) I thought the first Evil Dead was better than the second.
TMNT Out of the Shadows. Brittney Ishibashi as a badass Karai, Rock and Bebop, the Kraang, more "brother time" with the Turtles Still had Megan Fox tho
Prometheus is so far the highlight of the Alien series imo but yeah, technically not a sequel Yeah, trilogies or on going series are kinda different than unplanned sequels. Doesn't it kind of count for Bond movies too.
I'm on holidays, just watched Captain Marvel again. It is a bloody good movie. Some bagged it, dont really know why If we are counting the marvel movies as sequels The best are: Captain America 3 Captain Marvel Thor 3 In that order
