Most people within the Joss Whedon/nerd fandom seen to think so.
I've loved him since Tucker and Dale. Then I saw Death at a Funeral. Those are really the only things I've seen him in.
With a name like Two Dick?
He is really odd on Suburgatory, but was great on Firefly.
He was great in 28 days. I thought after that he'd always play offbeat characters.
in a Keram (or "Keram") thread, the OP said that Marcia Cross and Adrianne Palicki were lezzing it up, which led me to ask if AP's relationships with guys (including Tudyk) were fakes. OP never answered me, but someone else said Tudyk was basically out on Broadway, and had slept with Paul Rudnick.
BTW, fuck Firefly, where they gave him very little to do. But his Dollhouse spot was great.
He did the voice of King Candy in "Wreck-It Ralph" and damned if he didn't sound just like Ed Wynn.
