Mistakes!!!Too many to even count..but I'll try

Rating: 1/10 (3 September 2019)

I can't believe we just sat and watched this movie. There are a million different problems with this movie. Be advised we have watched all of the other Marvel movies, and have begun watching them over again with our children, and we feel totally disappointed with this last installment. I could go on forever on how it doesn't make any sense and is so disjointed... Spoilers ahead.
1. Why were there no paradoxes with the amount of interaction Thor had with his mom, Tony Stark had with his dad, and Captain America had with himself? Even Nebula met herself and then killed herself...Why didn't it impact or change anything in the future?
2. How come Tony Starks' daughter still exists if Thanos didn't get a chance to kill everyone in the first place? Wouldn't that negate the other off shoot time period?
3. How come Gamora was alive for a moment,(she lost her life due to Thanos in Infinity War) but Black Widow (who lost her life as a part of the same ritual)was dead dead? Never to return again?
Other troubles:
4. How come selfish Hawkeye gets a happy ending with his family after he killed his friend, and also went on a killing rampage prior to getting everything back?
5. Why did they ruin Thor and Hulk? They made Hulk the "smart hulk". He was straight up annoying. Thor was plain out childish. Why does the chosen ruler of Asgard, choose not to rule Asgard, and instead gives the job to Valkyrie, if not to merely push the feminine agenda and female power movement we are currently in?
6. Why did they make all the females go up against the army, alone at one point during the battle without males? Again, it felt like a commercial.
7. Assuming Captain America stayed in the past implies that there are two Captain America's in that same timeline. Eventually, it would cross over to the time when Captain America unfreezes. This would imply he is living his life in secret with Agent Carter, but then that doesn't make sense, because the old Captain America ends up on that bench in the ending timeline in an old man's jacket.
8. How come Captain Marvel doesn't age? She has been the same age since the 1990's. This wasn't explained in the movie. Although not a big concern, but something to note.
9. How come all the characters had no depth to them whatsoever, even those we have come to know and love? They were all one note and disjointed. None of them acted in the same way they had in previous movies.
There are many more plot holes and disappointing elements, but these are the ones that primarily stood out. I realize it has been explained away by saying there are multiple timelines, however the multiple timelines argument, will not give me back the three hours we wasted by watching this movie. We really hoped it would get better as time went on, only to find out it was about to get worse. So disappointing!! A big let down.
