Ah, well that makes sense with Angel. That first year was very sort of...unfocused, they've said they were trying to find a tone for it, weren't sure how dark to go, or how much to focus on the detective stuff over the supernatural, all that type of thing. It picks up a lot once they exorcize the big art-deco hotel in...I think the first episode of S2? Memory's fizzy. But yeah, it moves away from the detective-case-of-the-week thing into a bigger epic narrative, lots of Darla and appearances by The Master and stuff, before going all multi-dimensional and totally crazy. Basically, once Lorne and Fred becomes regulars it's maybe even better than Buffy.
And, hey, I love Buffy, even the middle seasons are a lot of fun. It just sort of lost its way a little after...maybe, what, S4? The Glory/Dawn season was awesome, I think the one after that was the Nerd Trio and Spike-romance season, that all gets pretty "blahh". Tara's awesome though in those seasons.
But yeah, we should search for a dedicated thread or somethin' I guess.
