I thought the Angel comic was kind of a mess. The artwork was pretty reprehensible-- there were entire swaths where I had to rely on dialogue just to figure out who was who, and since the dialogue wasn't exactly top-notch, that didn't always work. Plus, at least for the first "season" story arc, they built up to a big climax... then threw in two entire issues of "First Night" flashbacks that completely killed any momentum the story built up.
The new Buffy movie is going to be so much worse, though.
