Wow, this is a really tough one!
I grew up with Buffy and I must say that from the first episode, I was utterly hooked! I've only recently watched the "Angel" series, and, while I wasn't in love with it right away, it certainly grew on me. Maybe a few weeks ago, I would've gone with "Buffy", but, I have my doubts now. I do like more the darker feel "Angel" has.
I think that, although, they have some elements in common, they're still very different and provide different type of entertainment. In my opinion, Buffy deals more with the whole process of growing up, while "Angel" deals with what happens next, the grown up life. And now, I can relate to both. Since, I tend to personalize every movie/ tv series I watch, this is very important to me. Maybe this is way it's so hard for me to choose. In my head, it's like choosing between the "old me" and the "new" one. :blushy:
I had this entire speech in my head, before I started typing. But, seeing as my dog is out of patience, I must bring this rant to an end. And I must, say, that, right now, it's a tie. They both have their high points and low ones. But, man! What a ride they both were! Oh, now, I want to watch them again! *sigh
