Random order:
Sports games: This is pretty much the only genre where I would really go so far as to speak of hate. I hate watching sports on TV, I hate playing team sports and I hate playing sports games. Simple as that.
Notably exception: Nintendo World Cup on the NES. Because it's just fun to beat up the completely helpless bots.
Racing games: Pretty much the same as with sports games, but there are a few more titles I enjoy. Mario Kart is always extremely fun and addictive if you're a group of at least 3, and I loved the older NFS titles.
Fighting games: For me it's just pointless memorizing of combos. I can play a few rounds with a friend, but it quickly becomes boring.
Notably exception: Super Smash Bros., because it has a completely different, and actually fun, gameplay.
Beat 'em Ups: See Fighting games, the same thing more or less aplies here as well for me. Just never could get into it.
Business simulations and City builders: Just boring and tedious instead of fun. No action, no story, no characters - just micro- and macromanaging.
Notably exception: Tropico, because I always wanted to be the dictator of a banana republic. I didn't enjoy Tropico 2, just because they made it a pirate setting.
Turn-based games: Too slow, and the combat system is often very tedious. I also think real-time systems are generally more immersive, which is something that's pretty important to me. To be fair though, I do like som turn-based games and I recently warmed up a little bit more to it - but if I had a choice I would still prefer real-time mechanics every time.
(This also includes faux real-time like NWN for example.)
MMOs: I hate online multiplayer and like most people already mentioned, it just feels like you never accomplish anything. Because of this reason, there is never a real story, and everything in it (the game mechanics, the behavior of other people, the HUD) make it pretty much impossible to immerse yourself in the world - so yeah, MMOs look like a great concept on paper, but I've never seen it work.
But to be honest, I've only played ones that tried to emulate the WoW gameplay. Maybe I would enjoy the ones that do it differently (like Guild Wars 2 or EVE Online) more? I don't know, but I'm not eager to try, to be honest. I also don't like the thought that a game wants to milk me after th initial buy, even if it's only non-essential items to buy. If I want a game, I want to own it completely.
