11.22.63, on Hulu
IMDb; TV Tango; TV Tropes; Wikia; Wikipedia

An 8-part limited series on Hulu, based on a book (which I haven't read) by Stephen King, who serves as executive producer, along with J.J. Abrams (and a couple of other people). When I first heard of the series in 2015, I had some interest in checking it out, but by the time it premiered in February 2016, my internet had been too slow to watch anything on Hulu for awhile. But then I learned that it's only available to Hulu subscribers, so I wouldn't have been able to see it even if I had fast internet. Even after I subscribed to Hulu (and my internet got faster), I didn't get around to watching it, and it eventually expired from the service. But it later was added to Netflix, so I still hope to see it there, sometime.

Battlestar Galactica: Blood & Chrome

This is a 10 episode prequel to Battlestar Galactica, which first aired online (at Machinima.com) in 2012. In 2013, it aired as a TV movie on Syfy. It's not officially online anymore (though I'd be shocked if you couldn't find it), but it's been released on DVD. I never saw it either online or on TV, but I'd probably like to do so, someday.

This is set after a few other, regular series that I need to get through before I can watch it. It eventually moved from Netflix to Disney+.

Looking for Alaska, on Hulu
IMDb; Temple Hill; TV Tango; TV Tropes; Wikipedia

This is based on a book I haven't read. I don't really know anything about it, but I probably saw a preview for it at some point and decided I wanted to see it. Then I never got around to it before Hulu removed it from the service, but I may buy it on DVD, someday.

When They See Us, on Netflix

I don't really know anything about this, but it's something I heard of at some point that sounded interesting.
