Lexington is/was going to be gay? Huh, that would have been interesting to see develop. I just thought he seemed like a kid when compared to the others. A smart kid, but a kid. Wonder how that would have been done back then though.
But a reboot of that today would hopefully be amazing. I haven't watched the show in several years, but it would be nice to take a back to back episode watch now that I'm older. The new reboot could probably tackle a few more themes as well if it wanted. One series of episodes that stands out the most was City of Stone or something. I remember just hearing Demona's "Alone" part, which killed me right where I feel. Such a well acted show too, that I don't know if people would be happy with the probable cast change.
Babylon 5 would be amazing too. Like Gargoyles, its been many years since I've seen the show (and in truth, I've only seen Season 2 until the last one), but I remember loving it a lot. In some ways, it reminds me of that Re-imagined Battlestar Galactica, which I loved to death (one of my favorite TV shows ever). Having a reboot in the same way as BSG (not exactly the same way of course) would probably sell me in a heartbeat.
And while I don't agree with Harry Potter getting a reboot, I agree with everyone elses posts about HP having a TV show similar to Game of Thrones right now. I don't know if the budget would be that spectacular though, and it probably shouldn't happen for at least 5 years or something, but it would definitely be interesting.
