I know I started watching REGULARLY during season 4 of Angel.
Hubby was out of work, out of town a lot doing odd jobs and generally making my life a living hell.
Icouldn't go get a REAL job because that left no one here to watch the kids, so I had to try and support the family from here. I was up all night every night working and then getting the kids up for school and laying down for a couple of hours and then back up.
Angel is shown at 6 and 7 am on TNT. Sometimes I was watching, sometimes not. Then I realized there was NO WAY to keep up that way. One day there was a baby, the next time I watched the kid was like 15 and seemingly evil, then the "hot chick" was sleeping with said evil teenager, then we had Angel going "evil" and suddenly the kid was better by comparison.
I was SO confused I finally just popped in a video tape and started taping it every day so I could figure out what the HECK was going on with this show!
That was roughly around the time Jasmine came into the picture...maybe an episode or two before.
I might have stopped and given up, had it not been for Season 5.
Two times through that and LOVING Spike, I decided to start watching Buffy at 7 am on FX.
