I've been a Thor fan since the Lee/Kirby days when he and the Warriors Three used to sail the universe in a freaking longship. Ego was originally a Thor villain and he fought Galactus, Mangog, Hercules and so many other powerful opponents on a monthly basis. His book was always the wildest fantasy of all of Marvel's offerings besides Doctor Strange.
Marvel cast the perfect Thor in Chris Hemsworth, but it took a while for them to work out the best way to showcase Chris' talents and Thor's powers. When they brought Taika Waititi on board and finally embraced the cosmic aspects of Thor's comic book history, we got to see the character we love on screen in all his glory. It is so great to see the movies display Thor's powers in such epic ways, after several appearances in which he was held back far too much. To paraphrase Cap from The Avengers, Thor has the lightning so he should light the bastards up. Watching him clear the battlefield with his powers or summon the Bifrost is such a joy. He should have been capable of that from the start but better late than never.
We can only hope to see Thor develop further in Thor 4, Feige willing. He is just too perfect now for Marvel to abandon him.
