I really enjoyed this episode! Best one of the season! The what if actually felt like a what if that could have played out. With episode 1, Thanos dying, then Ronan coming to Xandar, and this random shield closed before Ronan could enter was all far fetched. Episode 2, all made sense, until Ego got beat so quickly by Peter and with the child saying Ego got into his head after exploding tons of planets, fully aware of it. Why couldn't Ego be in Quill's head while he was killing him? Episode 3, well come on, that Avengers tower heist didn't feel like a threat. I'll give it a pass because it was a Christmas episode.
But E4 made sense and felt natural. What if...? Tony didn't make it through the portal in time. Makes perfect sense. They also didn't go through a montage of paintings to show us it, they literally animated the What if that occurred. Small difference, but worth it.
Also Tony was insanely well written! Like what!? The writers defiantly love and understand these characters. Unlike other characters, Tony was pushed aside last season, and was present in 4 episode, because, well he's Iron Man. But here you get more to the character, it adds on. Like the doctor strange episode and the Ultron episode, Tony got extremely good character development! Gamora was good. Like okay. Again my biggest complaint, add more time to the episode. I'd sacrifice the 20 minute Christmas episode to add more time to some of these episodes. Because they could really use it. Jeff Goldblum was fantastic in this! I just love the character interactions, this is what made me fall in love with season 1, and what they continue to do in season 2, just this episode really shows!
JUST PLEASE, for season 3 add more space to breathe! For example we could've used a fight for Thanos at the end! That would have been awesome! Tony and Gamora fight against him. That would have been perfect.
