I think it's far easier to animate the characters themeselves in Poser than in Lightwave. I love the control the dials give. I wish the graph editor was bezier based though. The biggest problem I see, as has been said already, is that it either takes a lot of time for an individual to do or a diverse staff and the money to support them (and keep 'em focused). I have several tests I did for the 4-minute music video animation I'm working on now in the "Animation" section of the Free Stuff. Both the "Baby Test" and the "Drum Test" were done almost a year ago. My Poser things (like "dude, you suck" were done before that. they were for fun so they took much less time. This one animation has taken soo long and it's only 4 minutes (including a 4 piece band, 6 warriors, 2 dancers, and a baby). Time is the critical factor. Most people don't have enough.

Before they made me they broke the mold!
