It doesn't mean he is not good or he fell off the acting boat. Matthew Mcconaughey does commercials for Lincoln and he recently one an Oscars and he is better than commericals. I honestly just think he wants to do them because they are funny.

I thought it was kind of sad that he's acting in television car commercials, he's much better than that
The commercial itself is quite funny and with my recent reintroduction to cable television (didn't have it for 3 years) it's not a bothersome advertisement, much better than most! But still, I think he's above doing spokesmanship for television ads.

It is funny! And very watchable since he's so good looking.
