Yes. The movie was Flashpoint Paradox.
This movie was a combination of the animated and the series version. There was almost nobody to extract from the movie so he just made this movie for fan value accumulation. Since the movie had both series and animated version the system would evaluate the movie in collecting fan values.
Any movie that was not based from his previous life is disqualified and thus he could never follow the comics and make better movies which he wanted to do for a long time but the system never gave him the option to do. He hoped in next update the system will allow him to do so.
The movie continued as now the boy has turned out to be Barry Allen, the Flash. The movie showed his origin as he was struck by a combination of lightning and an experiment gone wrong. After realising he could run fast he started doing good deeds for people. Fast forward into the future where he was battling many evil people and a villain named Reverse Flash.
The audience noticed one thing, it was that when Barry and Reverse Flash ran it produced the same color of lightning as was during her mother's death. After a fight against the evil villains with the help of Justice League, Barry was able to stop Reverse Flash in killing everyone in the city.
But Barry wasn't happy even after fighting all the crimes and he did something which none of the audience expected. He time traveled to the past to save his mother. This was where he realized that her mother was killed by Reverse Flash. And he even saw himself. Barry ran to save both himself and his mother. Since Barry had changed the timeline now the one who was fighting the Reverse Flash at his old home vanished.
Barry then returned to his own time as he knew he had saved his mom and their family would be whole again. As he returned to his time he was happy to be with his family again but soon understood that something was wrong with this world.
Atlantis and Amazon were at war against each other. There was no Superman in the whole of Earth. Barry realized he needed to stop the war so he went to find Bruce Wayne. There too he got the shock of his life. It was Bruce who died in that alley that day. His father Thomas Wayne took the mantle of Batman while his mother turned into Joker.
Cyborg was present in the universe but there was only so much a single man could do. This was where the people saw a new superhero. Shazam. A group of children when uttering the world Shazam they could turn into a single entity which had powers like Thor. Hal Jordan didn't become the green lantern as the lantern ring never chose him. And the government captured Abin Sur's alien ship.
The movie continued as the whole situation went from bad to worse. Flash tried to help everywhere he could but the war between Amazonians and Altanteans destroyed countries after countries. And nothing the countries could do to stop it.
At the end Flash understood that this whole thing had happened because of him. The Reverse Flash showed up telling him that this world was his creation. This world was created because Barry Allen wanted to save his mother. After a fight between him and Flash, surprisingly Thomas Wayne was able to kill the Reverse Flash with a gun as he had let his guard down after beating down the Flash.
Meanwhile Arthur who was losing the war unleashed Captain Atom. Many recognized him from the Justice League Unlimited animates series. As Captain Atom was unleashed this caused a massive nuclear bomb capable of destroying the whole planet.
Flash who was been beaten down understood he needed to go back in time so that Reverse Flash could kill his mother and stop himself from saving the other him. So that's what he did. He ran like never before and reached the same old home only to stop Reverse Flash from killing the young him. He had to let Reverse Flash kill his mother. This was one of the most toughest decision he took but he took it to save everyone.
Barry then returned back in his time and saw everything was back to normal. Though there were changes but that was acceptable as he had messed with the timeline and no broken timeline could be put back in place exactly as the previous one.
Barry even brought a letter from Thomas to Bruce. He was thankful for such a gift. Now everybody understood why Flash had said that this movie wasn't really a happy one.
"So now there are two timelines, the real timeline and a little bit broken timeline." Tony said as he understood time travel pretty well and it's implications.
"Yes."
