I agree. At first I liked CGI and what it could do, but now I prefer the old methods; they just feel more solid, more mechanical, and when you're talking about ED-209, that can only be a good thing. If nothing else, there's more artistry to appreciate. 90% of CGI leaves me underwehelmed. The Star Wars prequels look like nothing more than the modern equivalent of the old Saturday morning matinees Episode 4 was meant to render obsolete. Puppet Yoda still rules, even though it would have been next to impossible to do his fight in AOTC, which was quite a twattish thing to do, apart from getting a cheap laugh, anyway.
Stop motion ED-209 is absolutely prefect. End of story.
What, are they going to make a CGI ED-209 do? A tap dance? You don't need CGI robots. It would take away the essence of the machine.
As well as ED-209, Peter Weller was also perfect. I'm sure other actors could be perfect too, but all Weller's successors so far have just looked like someone in Robocop fancy dress. They didn't move right, they didn't act right, Weller did.
That's me done. Your move, creep.
