Is there a TV show or movie(s) that you think Hollywood should either reboot, remake or expand upon? I'm sure you have nostalgic memories of some thing that you used to watch and wish there was a show like it today.
As for myself, I would hope that they bring back Buffy the Vampire Slayer. It was my favorite show growing up, and I have many fond memories of it (even though they used a double for all her fight scenes
). I don't necessarily want them to remake the show, but rather expand on it's lore. Perhaps some evil being finds away to reverse the "multi-slayerizing" of all the potentials and giving us an entirely new singular slayer. And who doesn't like watching a girl/woman kick butt!
