I'm OK with the effects as-is. At least they're the same effects as the original, though that's a double-edged sword.
I'll take lousy model work over lousy CGI anyday.
I think the point was it'd be decent CGI since they wouldn't have to worry too much about all the crap they have to go through (and it seems, mess up) with the model shots.
CGI gets such a bad rap here but it's not just a black and white "model good, CGI bad" situation.
There's good and bad of both kinds and seeing some of the poor work on this disk, (and even the good stuff making the 2ft model look downright awful, for example in the wormhole of Time Squared) I'm beginning to think they should've just CGI'd the whole lot.
Couldn't have been any WORSE, could it?
