Actually, like what some of the other guys are saying, surprisingly in hand it does. Specially with proper lighting highlighting the cheekbones, eyes, etc. It looks a lot like Depp.
I went and saw this in the window of Forbidden Planet yesterday, and I have to say I found the likeness to be quite weak I'm afraid.
Imo you shouldn't need to squint, use special mood lighting or whatever to see a likeness if the original sculpt is good enough. These things aren't cheap, so expecting a strong facial representation of the characters shouldn't be an unreasonable request I would have thought.
