if you like:

1) acapella (acafellas... lol..)
2) dance moves
3) duets/harmony and melody singing
4) songs with groovy beats (it's my life and confessions mash)
5) some heart touching moments (like sue sylvester and her sister..)
6) hot six-pack-ab jocks (where i think there are only 2..)/cutesy cheerleaders (erm..)

then, you should definitely watch glee. (not sure about the story line though..)

cuz those are the reasons i'm addicted!
