Trying to wrap too many stories and not doing it well

Rating: 5/10 (24 April 2019)

It's way too long. There's way too little fun or humor. Since it's yet-another-time-travel movie, it's not very interesting. Though they try to take a new spin on it (explicitly stating that "it doesn't work like in Back to the Future"), they end up with the same usual time-travel-silliness. The whole "multiverse and multi-timelines" is thus pretty inconsistent and weird. Sure, this is a comic-book movie, things don't make sense, but, still, they should at least be somewhat consistent.
We never quite get why this chain of events is the only one out of 5 million that works and why had Dr Strange chosen it.
And the whole "can't undo real deaths, only the Thanos-induced kind-of-deaths" is not explained (sure, it probably would not make sense anyway, but, still, it's kind of important and they don't even try).
Thanos goes full-blown villain, which is not in line with his character.
It also doesn't wrap up the story for all of the original Avengers. You kind of get why are the ones that are still here the "chosen ones" (clue: this is a business), but, still, it's a "conclusion of a story that is actually _not_ a conclusion of the whole story".
Even for the ones that are done, their conclusions are not well done, are somewhat cliched, predictable and un-interesting. Iron-Man fairs best here, but, still underwhelming.
On the plus side, from a general movie quality, this is better than Infinity War, it's better connected and the pace is better. Taking time-travel-silly aside, the story is OK. Although there a few "feminism in your face" moments, it doesn't go overboard.
Acting is good enough, but, it could have been better. Some things didn't work, like Hemsworth's take on fat Thor, others were just not very good (ScarJo as the "no-nonsense leader of the free-decimated-universe" and Chris Evans' take on Charlie Sheen - like Anger Manager) while the rest were just OK - foremost RDJ. But, the thing is, we've seen these actors do better, it's bad they couldn't do it again.
Bottom line, as a kind-of wrap-up for some characters, it's OK, worth a watch. But, on its own or if you're not into the characters that were "wrapped up", it's not.
