Season 4.
I just love this season so much! It was the perfect balance of drama and comedy.
You had:
*several scenes with Rosie and her girlfriends having nights out which was fun.
* The Mark drama intensified ie: birth control.
*Roseanne's overall demeanor was perfect and my personal favorite.
*The whole feel was just very calm before the storm.
When this season ends I always feel a bit sad lol because I know season 5 (Which is terrific) is full of drama and then season 6 in all its mean spirited glory comes to stay.
