Angel - Complete Collection [DVD]
Over all I really liked this angel box set. I bought it with out ever having watched an episode on TV, only ever seeing Buffy before, (which is also a good show and DVD box-set, so if you liked angel I'd would recommend that you buy that as well if you haven't already.) and was quite impressed with it.
Darker than Buffy with more adult themes, it depicts a good gritty view of LA with horror and comedy entwined neatly with it, (Plus the added fact that LA is inhabited by demons and that Angle himself is a Vampire.)
Season 1 and up to half way through season 2 are very good showing Angle's constant battle to regain his soul by working for The Powers' That Be, against the evil supernatural law firm Wolfram and Heart. From then on up to the beginning of season 4 the show gets a bit depressing. Season 4 was still quite dark - but not depressing (with the return of Angelus) - which made for an interesting season. Then season 5 was another interesting one not so dark with many twists and turns, plus the return of Spike.
As I said before, I do recommend this box set, if you can afford to splash out that is.
