Firstly, punctuation: what is the reasoning for including such silly punctuation as "?!?!" That sort of punctuation simply does not exist. A question mark is perfectly adequate. Your title makes it seem like you're in my face, screaming your question at me like some sort of ten-foot tall gerbil on cocaine.
Few sequels, IMHO, have been better than the originals. Some have things that are better than other things in the first, but very few are truly better than the original.
A few ones of note however: Baldur's Gate 2: Shadows of Amn, Zelda: Ocarina of Time, Diablo 2, and Icewind Dale 2 and Super Mario Brothers 3.
