For all the spectacle, it turns out shallow

Rating: 5/10 (27 April 2018)

It feels like a series of related, high-level commercials. It never stops, always wanting to make an impact right-away, never allowing time for things to grow. Mostly by blowing stuff up, but in all other aspects, too.
Humor is a bunch of one-liners. Growth (by, say, Teenage Groot) is an "event" - "from a tablet-playing teenager to a hero in 1.4 seconds".
When it does try to break that pattern, mostly w/Thanos, it doesn't do much, merely stretches the time-base, taking things into slow-motion, yet still the same low amount of things actually happen.
Not to mention that men show more emotion than women in this movie. Methinks #TimesUp for this silly feminism already.
The biggest problem is the finale, where any semblance of sense is lost, especially since we know Spider-Man and Black Panther have planned sequels, so, their "deletion from existence" at the end will not last. Hopefully it will not be some big "time-reversal" event, or this will start to look way too much like comics.
Bottom line, it's watchable, but not very good, worse than original Avengers and, while different, of similar overall quality with Age of Ultron.
