The 2nd Superman, the Alien(s) sequel, Chris Nolan’s Dark Knight and Rocky 2 were successful financially and will stand the test of time. Blade 2 was more than OK as well.
The 2nd Resident Evil was dreadful, the 2nd Mummy was NOT necessary and the 2nd X Men was cornball cliche.
Yep...Aliens was a keeper.
On the plus side, Patriot Games and Clear and Present Danger were good. But then again, you can't really count movies made from a series of successful novels as Hollywood sequels.
