OK, some people will kill me for this, but here are some games that everyone else splurges over, but I absolutely hate.
Resident Evil 4 - Why do people like this game? It was INSANELY boring and repetitive, I got to the area where the house was being overrun with zombies, and I said "THIS IS BULLSHIT" and returned it in exchange for Ikaruga. The sad part is that by buying this game, I missed a chance to snag the exceedingly rare Bloody Roar 4 for GameCube. I've never liked RE games, and whoever says this game is different is completely full of shit. You're still a f*cking army tank, but now it's an over the shoulder Border Patrol simulator instead of a survival horror game.
Halo - This game isn't really that bad, but it's not really good either. It's just a standard FPS, with a generic story and weaponry. Why so much hype? And why only hype from the jock-types and rednecks? Goldeneye pwned this shit.
Grand Theft Auto - OK, I LOVED Vice City, and I still do to this day, but this is like Pokemon or those homojock sports games. Every year, new graphical polish and maybe one new feature, and like a new soundtrack. WOOPTY-DOO. It didn't take me long to jump off that boat.
World Of Warcraft - I don't even care why people like this game. It's retarded.
Killzone - I FINALLY figured out why everybody likes this game! DENIAL! Microsoft has Halo, Nintendo has...something, I guess, so PS2 fans have to get behind soemthing, even if it's crap.
Call Of Duty series - Call Of Duty 1 was AMAZING. That is the first game that made me feel like I was actually watching a movie (Metal Gear Solid was like watching an anime or something, not that cinematic). COD2 was great as well. But COD3 was RIDICULOUSLY HARD, and 4 is going to ramp it up even more. Massochism, anyone?
And that's about all I can think of. What popular games do YOU hate?
