I also think that Marvel copied the NBC show Quantum Leap because that's what Loki reminded Mom of. I think I might give Loki a watch myself after my mom watches it to see if I like it
I don't see it yet. In Quantum Leap, Sam jumped from body to body to fix wrongs. It seemed like from the trailers it was going in that direction but it went a different way in episode one. Loki didn't take the characters place in the first episode. He actually ended up being that person.
