offhand I can think of

Friends seasons 1 and 4 (94-95, 97-98)
Buffy seasons 2 and 3 (97-98, 98-99)
Roseanne season 5 (92-93)
Facts Of Life seasons 2, 5 and 8 (80-81, 83-84, 86-87)
Sex And The City season 2 (99)
Ally McBeal seasons 1 and 2 (97-98, 98-99)
Roswell season 1 (99-00)

any others come to mind? These are seasons of shows you like that you consider some of the best ever

The first season of Oz was amazing because I didn't know what the show was about and when I watched for the first time I was blown away.
