They changed a lot of things that previous GTA players were accustomed to, although I'm sure that's not of the higher complaints on the list.
This is what I dislike in GTA4. You can agree/disagree, whatever.
1) Game moves incredibly slow, both movement in cars, walking and storyline. Basically everything. Hijacking a car, breaking a window, hotwiring it. I don't want realism, JUST GET IN THE CAR!
2) YOU HAVE TO HOLD "A" (or PS3 "X") TO RUN?! WHY!
3) They removed Ammu-nation. (Classic GTA material)
4) No customization like SA
5) No car customization
6) No sense of "power." You don't get a mansion with bodygaurds, you don't have a gang per say. You're just average-ish with a lot of money by the end of it.
7) Niko Bellic is exceptionally lame (but the supporting characters aren't! I really liked 'em)
8) Combat could have been better
9) Online is super duperly extraordinarily whack.
10) Useless garbage such as watching T.V., Cabaret Club, Internet etc etc...
11) No planes, bikes, nor jetpacks.
12) Less cars, bikes, weapons etc.
13) No memorable missions!
