It took until in The Avengers to properly nail the character, but thankfully Marvel did strike gold (or rather green) with casting Mark Ruffalo as the afflicted Bruce Banner. It should be fun to see him team up with Thor in the upcoming Thor: Ragnarok.
Though he is often overshadowed by his on-screen brother Loki, it shouldn’t be forgotten that Chris Hemsworth gives a great turn as the God of Thunder, making a potentially ridiculous character into a rootable, noble prince.
She’s not the best female hero the MCU has to offer, but you can’t deny that Natasha Romanoff has got style. With her assassin history still largely unearthed, the character is crying out for her own spin-off movie. Hopefully, they will get around to it eventually.
