The Loki in the MCU movies was interesting, and a true villain in the begining. Then, through Thor 2 and 3 movies, he transforms in a belivable way, because his mother is killed, because he finally bonds with his brother and because Odin accepts him in the end. So he becames a hero by the end of Phase 3.

The Loki in the TV series is lame. Altough the series picks up right after the battle of New York, he is suddenly a good guy. Friendly and sensitive. So this was a waste of time. No season 2 for me.
