A Horror Movie Masquerading As Science Fiction?

"If Danny Boyle's 28 Days Later was a horror movie that effectively masqueraded as science fiction, the follow-up would make George Romero run for cover." [This Is London]

Not sure if that is good or bad? I will go and see 28 Weeks Later soon anyway, because 28 Days Later scared me lots. I mean, zombies that can run! ArrRgggGhhhHH! There goes all our zombie contingency plans.
