I'm probably alone in this but this incarnation (visually) still doesn't look better than First Class beast to me at least. I know the articulation (or lack thereof) of the Beast make up/prosthetic was a letdown for most but on a pure visual sense I still really liked how he looked in First Class.
I know I'm alone in this but just thought it would be worth mentioning seeing as FC Beast gets very little love.
I do enjoy however that there does seem to be a clear evolution of the Beast look from FC to Last Stand. I like that he's looking progressively more humanoid.
My biggest gripe with the FC beast were the lips--you could tell very easily when they used computer animation to make his lips move, and it was completely unnecessary. One thing X3 did well was the Beast make-up; Kelsey Grammer definitely looked beastly and blue, but still had enough human features for him to express himself.
I remember cringing in the theater when I saw FC's Beast in the hanger bay. They just went overboard on everything, especially the lips. The only thing I'd change about the X3 version are his eyes--make them that yellow-orange. That's it.
