when it comes to reproducing creatures, puppet based SFX just suck compared to CGI. CGI can reproduce more natural behaviour and motion of a creature. In the end they both look fake.

I'll take the less-than-fluid movements of puppets over the plastic surfaces and weightlessness of CGI any day.

I just don't see the reason in investing great amount of time, effort and money in making a stop-motion SFX with a puppet. Especially when it usually look very unnatural. The way to solve this is either putting a guy into a costume or using CGI.

You do realize that in this day and age, the herky-jerkiness of stop-motion can be corrected, don't you?
