I dislike a ton of things about it. Mainly, though:
1. Sense Motive, Bluff, Diplomacy, etc. ... roll your skill rather than play your role.
2. Spot, Listen, Search, etc. ... "roll to see it". Takes away the search mini game.
3. As written, most Fighters can't Intimidate anybody (CHA dump stat and skill points best spent on Climb and Swim), whereas the 130-pound puffy-shirted poofter with the lute all the sudden turns into King Kong (skill wh***, super CHA) when he threatens somebody. Basically I hate the social skills and everything to do with them.
4. Gargantuan stat blocks for all monsters (even non-Gargantuans). As if I give a dire rat's patoot what an owlbear's Wisdom score is. KISS principle here.
5. Combats that take an hour or more apiece. What a bore! This comes from may things: grid obsession, modifier mania, gargantuan stat blocks, analysis paralysis-inducing options ("well, if I move over here and start a flanking grapple I'll get +3 from my Improved Grabass feat... but I could also move over here and throw a +1 bocce ball which will give me an additional +2 from my Deadly Bowler prestige class and a +1 from Point Blank shot and....").
6. Dungeonpuke. Or was it -punk?
7. Character Builds. The D&D version of M:TG deck building. A knife to the heart of what D&D is all about.
8. Stat booster items and stat buffing spells. A bland, annoying mechanic that turns your 1 hour combat against 5 hobgoblins into a 2 hour combat against 5 hobgoblins.
I could go on... but that Thanksgiving turkey ain't gonna cook himself.
