I never got into Buffy or Angel when they first aired. I have been watching the Buffy series on DVD. I have watched up to season 3. I know season 4 is coming out in June. Angel season 1 is out now. So here are my questions: 1. Do I need to watch Angel S1 and Buffy S4 intertwined? 2. If so then in what order? I want to watch the series the way there were meant to be watched when they came out. I don't want to go out and buy Angel season 1 and then watch it only to find out that some episodes carried over into Buffy or vice versa. I appreciate your help.
