Also the Wrath of Khan a much superior sequel to the original.

Jaws 2 a decent follow up to Jaws, less said about 3 and 4 the better.

The 1st 2 Indiana Jones follow ups were excellent too, the last 2 not so much.

Batman Returns was an excellent sequel too.

Karate Kid 2 was decent too. Cobra Kai is good fun if you liked the original Karate Kid

The recent Beverly Hills Cop is a good watch after the horrible 3rd from the 90s.
