Full House: I watched it when I was a very young kid, but not since and have little memory of it. I love Fuller House now so I'd like to watch it on a streaming service.
Soap: The Three season recap retrospectives (at least the one with Bea Arthur). I don't want to buy a vcr just for this.

Although I've seen a lot of "Make Room For Daddy", I've never seen the episodes with Jean Hagen as Danny's first wife.

I would've liked to see the spin-off of December Bride..."Pete and Gladys", with Harry Morgan and Cara Williams.
