28 Weeks Later - Loved it (and much more than 28 Days Later).

Couldn't agree more! love them all. Like to add few more...

Son of Frankenstein (1939)
Inferno (1980)
Hammer Frankenstein sequels:
The Revenge of Frankenstein (1959)
The Evil of Frankenstein (1964)
Frankenstein Must Be Destroyed (1969)
Hammer Dracula sequels:
The Brides of Dracula (1960)
Dracula: Prince of Darkness (1966)
Dracula Has Risen from the Grave (1968)

Agree with most of the films mentioned already but will add-
Leprechaun 3
Amityville 3
Hellraiser: Bloodlines
A Nightmare On Elm Street 3
Halloween 4
Not really a sequel but Zombi 5:Killing Birds

Halloween 4 and ANOES3 are pretty well-liked, never seen much if any disliking for them.

I've seen bad reviews of both of them.

Hellraiser inferno

House of Frankenstein. I always enjoyed it on a basic level, but as time goes on, I find I like it more and more. It's a good sequel to Frankenstein Meets the Wolf Man and manages to add Dracula and a bunch of other cool stuff.

It brings in a tragic romance between poor Larry Talbot and the gypsy girl. Boris Karloff returns to the Frankenstein series, but as a mad scientist (he's actually pretty darn nutty!!). J. Carroll Naish is good as his hunchbacked assistant Daniel. John Carradine as Dracula. Nice matte paintings. Animated Dracula-to-bat transformations. All in all, a good production package with a good cast.
