Poorly explained time traveling concepts

Rating: 6/10 (15 July 2019)

I strongly agree this movie has everything all marvel fans hoped for, with amazing special effects, epic fight scenes and much more, but one thing that made quite disappointed was the solution to the problem previously presented in infinity war.
They decided to solve this entire situation using time traveling, which is completely fine if you do it the right way. The producers and directors made a bold move to present a whole new concept of how time traveling works, differing from classics of this genre, like the "back to the future" and "terminator" franchises.
In my opinion this whole decision becomes an issue when they're explaining their plan is going to work, since they take a really limited time of the movie doing that. I think they should've invested more time in that aspect, considering they had a three hour film and barely used fifteen minutes of that actively exposing their plan, basically saying that they were using time traveling as a solution and it wasn't the same thing as in "back to the future", not making the audiences understand them just so they can make a silly joke.
I later understood what they meant, but that required further research on the subject after the movie, and the audiences should leave the theaters understanding the whole movie plot, something that didn't happen to me and others.
