I watched this without knowing anything about it at all.

Some people argued, some people shouted back at them, then some other people chased some other people, then they all had a fight, then had to make some decisions.

Then a load of monsters and superheroes turned up, then all of the same things happened again but with the superheroes involved this time and with explosions too and more fighting, it seemed to be over something important.

Then one of the teams won, which seemed to be the right result looking at the people I was watching it with.

I had a feeling I had seen this or a similar story in something once, when I was a kid but everyone else who watched it with me seemed to be interested, so should keep the kids amused for a while.
