'Supernaural' always gets me... it doesn't seem to be shown anywhere here in the UK, I have to wait and depend on my bro to get them for me. I'm in the final season 15 ep 6.
I find a lot of good humor and fun in the show and references are so funny. Let alone the drama of what they're hunting and it doesn't take itself too seriously... I love it.
It's the same reason that DVDs purchased in the USA won't play in the UK and vice versa. The TV and movie companies can make more money out of selling the broadcast rights to their shows separately in each region than they can by selling them on a worldwide basis.
It also enables those selling the rights to get local broadcasting organisations to compete against each other. So, for example, a film distribution company can approach Netflix UK, Amazon UK and Sky TV (who control satellite broadcasting in the UK) to see who'll offer the highest fee for the UK broadcasting rights to a blockbuster movie. In the USA they'll approach a different group of companies, and so on around the world.
I've heard a lot of good things about The Boys, although I'm more familiar with the comic book it's based on, given that it's written by Garth Ennis. Ennis was responsible for one of my all time favourite titles, Preacher (with the late Steve Dillon), which has also been turned into a series.
Back to Being Human. It was so well written, and the original cast had such a great chemistry. I am probably due a rewatch sometime.
