As Sedai said before,
Angel was an top notch show that stood on it's own two feet. It distinguished itself from
Buffy and is easily the best spin off from any show ever. At times it even eclipsed it's sister show. Like, the first season of
Angel was a far stronger season than season 4 of

And despite having some of the best action/fight sequences I have seen on television to date, season 4 was a mess. That beast storyline ended prematurely and it seemed like Whedon didn't or Minear or whoever was mainly in charge at the time didn't know where to take the story. Too many anti-climaxs in that season, plus even though he is by far my favourite villian in the Buffyverse, the return of Angelus didn't seem to serve much of a purpose to the overall story except to please long time fans.
So yeah, it's fair to say that
Angel was up and down between the end of season 2 to the beginning of season 5..which was an excellent season if I do say so myself. As awesome as season 1 and a satisfying way to end the series.
So yeah, ignore the bollocks that is
True Blood, get the boxsets, sit back, crack open a can of beer and enjoy
