What If? was the first Marvel Animated series. It is considered cannon to the MCU given most of the voice actors played the characters in the MCU. There are a few exceptions.

What If season 1 was highly enjoyable the first time around and is still that way the second time around. The animation is well done, and it has good episodes. I really enjoyed season 1 and am very excited to watch season 2.
