you know what i find funny about the complains about carol being a deus ex machina?
tha nobody complained about Thor having stormbreaker as an upgrade.
like literally, if he could have forged stormbreaker on ragnarok,
Uh... What? Are you actually complaining about Thor's storyline in Infinity War? He lost everything. He was driven beyond despair to a place very few people ever come back from, where he was quite comfortable knowing he'd either kill Thanos or die trying, and we have no idea what's going on in his head now that he knows he failed. All that power and he still couldn't stop Thanos, who even gloated that he should've aimed for the head before disappearing. That sort of thing would be gnawing at him so bad.
Thor's storyline has been fantastic since Ragnarok. I don't even know how anyone could complain about that.
