This is actually one of the better fan-fics in my opinion. It is close enough to the original to be nostalgic but Loki skews the plot enough to make it feel fresh and gives an interesting perspective on the events. As mentioned, Loki trolling through the MCU would be hilarious. I tend to lose my interest in fan-fics that go completely off the rails and only mention that the MC's plot is happening parallel and away from cannon.
