I'm co-writing two of them with artist Ed Kline. Obviously that makes me biased, but say what you will about Ed's art, he has a real vision of the worlds he's creating. That's what every artist, CG or otherwise, has to have to create a good comic.
They've put in the effort to tell a story despite the fact many of the people that make CGI comics do not consider themselves artists. Nothing about the amount of work and effort and time and creativity changes just because you use CGI. There is the same dedication and talent for storytelling, or just presenting a situation that makes the reader feel as they intended, as any other comic out there!
If you're a CGI comic artist and people wanna say that somehow makes your art less valuable, or anything like that... stuff 'em. You're awesome. Keep it up.
They're a lot of fun and when I see them, it reminds me of the times I used to take my action figures and dolls and have them play. And I mean that in a good way. They're fun looking and different. While I still like doing comics the traditional way, I appreciate CGI as a beautiful and unique art style.
CGI takes the focus off the technical components of drawing (darn you, 2 point perspective) and allows the artist to focus more on the story. Plus you only need to make a character once (unless they get a new wardrobe).
I've read cgi comics where the creators' understanding of emotion through character acting shines AMAZINGLY. When you know how to place the camera to give the reader more information about the feel of a certain scene, the added realism of cgi models is a huge plus!
