Okay. You asked for it, mate. 😉
Pro's of Angel:
1. Angel himself. There's so much contrast in character between the two series, there's this whole new beautiful side to him that we didn't get to experience in BTVS. Oddly, he came out of his shell after breaking up with Buffy. (Don't kill me Bangel's)
He's brilliant in ATS. He's actually funny. So, if you don't watch ATS, you won't experience this new and improved Angel!
2. Illyria/Fred. AHHHHHHHH. C'mon, Amy Acker is absolutely freaking amazing, I don't know how she accomplished such a dramatic change in character with Illyria. Fred is this sweet, insanely intelligent, friendly girl who you have to love because she's too damn nice not to! Then, BAM, Illyria comes along and you have to love her just as much because she's a superpowered chick who is.. blue. YES.
3. Lorne. Andy Hallett. Enough said. You'll never find a character like Lorne, played so beautifully by someone like Andy. Amazing. Plus, singing green demon, who can beat that?
4. Cordelia's personality change. I loved Cordy in BTVS, don't get me wrong, but she really blossoms in ATS. You don't see Cordy's true personality until you watch ATS, she truly turns into an actual person who cares. I'm sure a fair few people can back me up on that one, seriously. She's awesome.
5. The dark plots. Don't get me started, there's a shock at every turn in season 4. I was just getting over one plot twist, then another one hits me right in the face. Clever, clever writing. The Beast? Scary ass dude with a major moisturising problem. Brilliant!
6. Wesley, Wesley, Wesley. Cute nerd in BTVS, cute nerd in ATS. Oh wait, he turns into a sexy bearded legend with no mercy. Did I mention I love ATS?
7. Doyle. Irish legend.
8. SPIKE IN SERIES 5 YESSSSSSSSSSSS.
I've probably forgotten some stuff but I'm way too tired to write more. I'm sure you can tell, as my sentences are getting shorter and shorter. Yay me.
I feel like I've spoilt a lot for some reason. I don't think I went too into detail, did I? Oh dear. I'm going to bed.
Cons: None.
