Poor writing and uselessly wasted buildup time, this was a failure by Avengers standards.

Rating: 5/10 (25 April 2019)

It's like Marcus and Mcfeely just said ef it and patched together some scenes to get to the final one that brings Thanos back to the center of the story. The only scene that really worked well was with Widow/Clint getting the soul stone which we all knew required one of them to die going in, so no big reveal here either.
It's just sad that the Avengers wound up looking so ridiculous and so incompetent in light of the much better previous movies. The few scenes with Marvel are just junk, like Tony and Nebula couldn't come up with a fix for the ship and are just going to die in space.. just completely weak and witless writing to make Marvel the hero. Garbage. Writing Thor into a complete joke and making New Asgard look like a dumpy little fishing village, Hulk and Antman seem clueless other than just a "lets DO SOMETHING' flash of mindless hysteria. Only Hawk is actually doing something that looks like accomplishment though we are given a 'morality lesson" on the concept of vigilantism, I mean of course COMIC BOOK character need morality lessons. More garbage from the Fliege/Disney soy based milk toast comic reality devoid of traditional heroism.
Of course one of the ALL TIME weakest plot devices in the history of plot devices is the one chosen here, time travel. Time travel has always been a weak link and poor option from the days of Star Trek whale saving to the modern Tom Cruise saves the day movies. Only the best written Doctor Who has remotely worked well in the time travel realm and then it was a mcguffin just better done than the other lame attempts.
Bad writing and crapping all over the history of the Avengers by making them look incompetent and always needing a bail out, is really the story here, it's hard to describe how many failures popped up from the end of Iron Man and a last second appearance of Pepper who doesn't even look all that concerned to a weirdly executed Gomara plot twist that leaves you wondering what the eff they were thinking. So much poorly executed and failure spells a huge letdown for the MCU. Mercifully now it's over since we know the main characters are now done and gone. Maybe a Doc Strange of GotG movie will be worth catching, but not much else.
Good bye MCU, what a shame you died such an embarrassing death and disrespectful ending from the so called creators, the Rousous and Fiege should truly be ashamed.
