I love his voice :\. I think his laughing can be a little forced and cheesy at times, but hey, he's missing a jaw. Regardless, I always look forward to the scenes with him in it. I love his "pathetic planet" line at Taris.
I don't really mind his suit either. Skintight red is probably pretty fashionable in the Star Wars universe, seeing as how all normal citizens seem to wear rags.
