once hated but now love the show

Roseanne- i use to not like this show but shortly after it joined Nick @ niite i grew to like this show.

Three's Company- at one time i didn't think i would this show but one i night i turned on the tv and Three's company was on tv land and i watched the entire episode and i love it and i been watching Three's company ever since

use to love but now hate the show
The CosbyShow-i use to like the cosby show alot but i now i hate that show ,i can't stand Bill cosby or the cosby show anymore i just do't even find the show or bill cosby funny anymore and iam trying to figure out how to get rid of the dvd.

I agree with Roseanne/Three's Company, but not with Cosby. Bill Cosby is probably the greatest comedian still alive. IS act was always fresh, funny, and almost completely unscripted, which made The Cosby Show.

Here are my shows I used to hate but now love:
Murphy Brown
The Jeffersons
A Different World
Mad About You
Growing Pains
Family Matters

Scrubs!

frasier- i wouldn't say hate but rather at first, i never understood it at all because i thought it was too 'intellectual' for my own taste. but after a few seasons it grew on me and i loved it

shows i once loved but now hate-
friends- it was good at the start but eventually, the longer it went on the more more and more i became sick of it. it is arguably the most overhyped sitcom, ever

just shoot me- i liked the first season but again, like friends, i lost interest and found it more and more unfunnier as it went on and on

Cheers
Seinfeld
Friends

I didn't care that much for them at first but now I like re-watching them.

Scrubs
Frasier
Still Standing
Discovered these gems through reruns, never got into them while they originally aired as there were too many other things on at the time.

Well when I was young (10-11), That Girl came on TV and I wasn't into it at all and thought that Don was kind of drippy. But when I started watching it on VHS 35 yrs later, I loved the show, everyone on it, and esp. Donald. I guess for me it was a generational thing. What you like as a kid/adolescent can change quite appreciably when you get older.

CSI: LV

I didn't care for The Odd Couple and WKRP back when they aired on N@N, but I saw them a few years later on different channels and I've loved them ever since.

The Nanny

Any T.G.I.F show(except Full House, I STILL cannot stand that show!)-This is probably because I hadn't seen that many of the shows since I was twelve. I was always out on the weekends so I never really seen a T.V show that aired on a weekend from 1993 to 2002.

Everybody Loves Raymond - I didn't hate it, but I didn't really like it, then I picked up a later season on DVD and its really good ... I'm waiting for Season 8 DVD to come in the mail today :D
