Sequels better than the original.

A lot of people say The Godfather: Part II is better than the original Godfather. I would tend to agree.

Terminator 2
For a Few Dollars More
Empire Strikes Back
Mad Max 2
The Dark Knight
Spider-Man 2
Lethal Weapon 2
Undisputed 2
From Russia With Love

Better than first one,not necessarily best in whole franchise.

The Good,The Bad And The Ugly
Dawn Of The Dead
Lethal Weapon 2

Jaws 2

Back to the future 2
Captain America : the winter soldier better than Captain America the first Avenger.

House 2
Desperado

Shrek 2

And an unpopular opinion choice Hellbound:Hellraiser 2. There are some haunting, iconic scenes and dialogue.

Ace Ventura: When Nature Calls is better than Pet Detective.

And I personally like all of the Friday the 13th sequels better then the original.
