SentinelShow ContentThe movie goes out of its way to explain why he did that tho so I dunno why you dislike it. Doctor Strange saw basically every possible future outcome thanks to the Time Stone combined with his magic, and knows the only possible outcome that actually wins the fight for them or has a chance. His actions after that moment have everything to do with the 1 outcome he saw, i.e. he knows the only way the Avengers eventually win is with Tony alive and with Thanos having the gems, as if they actually tried to keep the gems away from him, Thanos would just kill everyone on Earth until he got them all as he doesn't care about just Earth but balancing the entire universe - the only way they have a chance is to give him the stones and fight back later. Strange's dust lines tie into this being his reason for the decision as well.
My dislikes of the films setup are:
* I didn't like that they didn't show Thanos taking the Power Stone from Xandar and the film just starts after he already has it - this might seem minor but it's like catching Thanos in media res of his journey, and even if it was an extra 5-10 minutes I think it would have been cool to see him gathering all 6 rather than just already having one of them. The opening of the film would have been even stronger IMO if it opened up to Thanos defeating the Xandar mooks for the Power Stone and Thor and his group come flying in to help them out. Audience gets hyped because the heroes are coming to save the day, boom destroyed in the same way basically. [/quote]
