Watch first episode of Twenty Good Years online

Lithgow and Tambor are both such outstanding actors that I hope this is a success for them. I have it on my "To Watch" calendar. I am interested in just about everything Lithgow (in particular) is involved in. I've found 2 or 3 new shows I'm enjoying and I hope to add this one to my list. Of course, virtually no one can save poor writing, so I hope the writers come through on this one.

That was a mistake.

And what's the deal with saying "first full episode of the new sitcom Twenty Good Years on it's video site" ? It is video site? Is that English? Shouldn't there be a possessive there? I guess old timers never learned English back in those old-timer schools.

Maybe.

Why was that first sentence all grammatically garbled? Is that old timer talk?
