I have seen it about 5 times over the last few years. That scene is still awesome, mostly because you know those are animatronix effects, but they work especially for that time period.
I think the script here will be decent....but I think many will gripe about the effects. For one, yo can't possibly expect them to avoid CGI in the year 2011. It is almost cheaper now to do it by computer than to try to bring the old make up crew back for a redo...not to mention, make up effects have even come a long way since then.
Bottom line, the Kurt Russel Thing would look completely different if done today and I think we just need to accept that.
They are avoiding showing the monster in most previews. I am assuming they are making last minute touch ups.
I'm going to see it no matter what.
I just hope they do it right.
