Men In Black
This is a given. Sci-fi alien hunting flicks are perfect for television series. A writer could even make it like The Walking Dead where the show isn't actually about catching aliens, but about the hopeless, apocalyptic world the Men in Black live in and the hope they all have to stay alive. All that matters is that we have the band of suit-and-tie heroes chasing aliens around the streets of New York City. The only real and difficult question to ask is who would play the black-suited duo?
