I had some school stuff I had to do from 6:30 to 9 during the week, and my VCR wouldn't record worth a shit. Basically the same reason I stoppe watching Buffy. By the time I got to watch more episodes I had already missed most of the season (The last Angel episode I saw was the one before She)
I'll probably just wait until it comes out on DVD. The Angel season sets come out every five months, right? If so, 4 comes out just in time for my b-day, and 5 will come out just in time for x-mas, so it works out pretty well
