I don't mean to be a jerk, but if Crackle is so much better, then Hulu+ must be horrible (I haven't signed up yet, so I don't know about Hulu+). I just went to Crackle's website and the only TV shows from the 50s and 60s were "I Dream of Jeannie" and "Bewitched." That's it!
From the 70s they only offer "Barney Miller," "Good Times," "Sanford and Son" and "Soap" (plus a couple of Japanese animated shows).
I don't know where you live, but if you dig out the old rabbit ears you'll find a lot of "over the air" digital substations (like
Antenna TV,
Retro TV and
ME TV) each have a great selection of older TV shows. Tomorrow they'll start airing "Burns and Allen" on Antenna TV -- looking forward to that. Looking forward to yesterday.
