Got to a late start, but finally finished IW and EG. IW was great for the most part -- other than Star-Lord repeatedly fucking the entire team over -- while EG kinda sucked other than that epic final act... and then kinda sucked afterward for all of the major continuity shifts. I can see why PO mentioned not being excited for the franchise's immediate future.
Also IW to EG had something of a gap. I guess the after-credits scene in Captain Marysue was supposed to kinda address that, but... it kinda didn't. It just made for a pretty rough start. And speaking of Captain Marysue, she really Marysued it up, with characters immediately taking to her (such as Thor's almost immediate "I like her") and -- to an extent -- praising her for her power. It's not even a matter of the character herself not being written terribly well, but it's like the writing all around her gets impacted as well. (Raccoon was all like, "You're awesome, you should be helping us more," and Marysue be all like, "But there are a lot of other worlds that need helping," and Raccoon be, "Oh, that's cool." Paraphrasing, but seriously, LOL!)
Pretty much everything in EG was pretty wtf. The core plan wasn't just out of left-field, it felt out of everything we've seen so far. The actual individual missions offered a neat retrospective, although the biggest aspect -- Thanos coming to the future WITH his whole previously-defeated crew -- was awesome and makes up for that other shit. Doubly so since Thanos gets some proper comeuppance and we get to see his smug smirk vanish when his army is met by the restored Earth allies. Then, after being forced to firebomb the entire field and put his own forces at risk, he watches his ship get single-handledly wrecked. And then he gets to witness his final defeat when Tony unleashes his own snap. All things considered, that was a great payoff to a long 2-part movie.
What was less cool was how they were worried about the impact of their plan and then Captain America just chooses to stay in the past, which seemingly contradicts those concerns.
Also I couldn't stop laughing at the blatantly fan-service-y/pander-y "she-roes" charge near the end. That moment just seemed so goofy, probably because they handled it in the most glaring way possible so there was no mistaking what they were trying to do and they wanted to clearly signal what they were doing.
