List of films where I think that a franchise was perhaps unnecessary. I may have enjoyed some of the sequels but a first film was good enough and ended good enough for it not to be continued.
I disagree with "The Terminator" (T2 is a classic) and "Home Alone" (Home Alone 2 is a guilty pleasure of mine, although 3 and 4 sucked, I can tell ya that), but other than that, great list.
Pirates - Didn't need sequels
Scream - Would have been great without sequels, but I liked them anyways, more so 2 and 4.
The Terminator - Although I prefer the first, Judgment Day was needed :D
A Nightmare on Elm Street - Didn't need sequels
Jaws - DID NOT NEED SEQUELS
Predator - Didn't need sequels, but I liked Predators
Home Alone - Didn't need sequels. ESPECIALLY NOT 3 & 4
