Just not the ending I was hoping for

Rating: 5/10 (26 April 2019)

Just a first impression. Minor spoilers only; not going to say who lives and who dies, though I will give a plot point or two away, so don't read on if you haven't seen it yet.
I'm a big fan of Marvel's movies, so don't think I am trolling. My honest opinion is that the movie is fun, has a three hour running time that doesn't feel overlong, but doesn't really do anything we haven't seen before, in the way Infinity War did. It lacks something and does a diservice to some of the characters by making them comic buffoons.
Time Travel? Really? More End Lame than End Game. At one point some of central characters reel-off time-travel movies, and they don't really come up with any variation on the standard cliches involving such movies. The redo of previous movies is enjoyable but hardly brilliant.
Really like Chris Hemsworth as Thor. The writers have turned him into a joke here. Not the actor's fault, he does a fine job, as do all and sundry with what they are given. I didn't buy what they did to Hawkeye at all. The Hulk has done nothing over two huge movies. He was ruined, too. Some of the film is much too broad in its humour.
So does this mean the the events of Winter Soldier and Civil War plus all the previous Avengers' movies didn't happen? Trying not to give anything away but parts of this fall into X-Men Days of Future Past territory. Or Deadpool 2. It's confusing and it feels like a rip-off. Cosmic Marvel seems to have taken over everything, and the more grounded movies feel like a thing of the past.
I will have to see this again before I give my final opinon. At present I feel a bit disappointed. Much of the movie is fine; the ending is a retcon., like Brand New Day in the comics. And I hate retcons. The central theme just didn't grab me. All in all, Infinity War, Winter Soldier, Iron Man and the original Avengers film were much better for me.
