I'm really liking these animated webcomics more and more. It makes a lot of sense and really takes advantage of the digital medium while still being true to comics.
For me, I prefer comics to animation in general, because with comics the reader controls the pace and can go as fast or as slow as they want. I think animation is great, but I usually can't sit through an entire movie or show without fast forwarding through parts. I like to just watch the good parts (usually the action scenes).
These short animations in webcomics are really perfect because they add such richness and excitement without changing the pace too much. It's enough to add to the experience and suck you in, but so not much where I feel like I'm waiting for it.
