Game:
Hype...oops, Half-Life.
Yes, it was a good game for the time. However, I'd played SiN before playing HL (thou few did) and the number of innovative gameplay elements in SiN went a lot further for me. Location based damage for one (vs typical FPS splash damage as in HL and most other FPS til Unreal Tournament made it "popular").
Movie:
Speed.
Okay, it was made in 94 so it' doesn't "technically" qualify for within the last 10 years, but so many people liked this film and I just can't stand it. Some of the scenes in that film are so bad it make my skin literally crawl...(shudder).
Band:
Pretty much any manufactured boy or girl bands, so "fill in the blank".
I don't mind talent and decent songs. But these things are often SO forced down our throats that it's just sad. Actually, what's really sad is the amount of "sheepness" people display in getting "into" these bands just because they are on TV/Radio 24/7.
