I have to say the CGI in the remastered eps was good all around, but I was really impressed by the D'Deridex reveal in "Neutral Zone". Perhaps it's just that I haven't "Neutral Zone" since the Season 1 DVD set came out, but I felt that the Warbird looked amazing. It seemed imposing, big and really well textured. There even appears to be a new design element, a sort of ripple or fold on the "wings" of the ship. I actually said "Whoa!" outloud upon seeing it. The CGI E-D looks good, though there are a few times I *know* it's a CGI ship and the illusion is shattered. But I have to say, the CGI is well integrated into the show and doesn't seem as alien as it does in TOS-R. (Not that TOS-R is bad, but you notice it more.)
Also, have we gotten a reason as to why that 2 seconds of Riker wasn't HD? Missing film I'm guessing.
