Avangers infinity war

All the reviews that say this movie has no plot are either trolls, idiots, or didn't are to take the time to watch previous marvel movies. Every single one of those ratings and reviews should be taken down and not added to the rating for Infinity War because of their fundamental lack of understanding. It's like coming in and watching the last 2 minutes of an hour long drama show and saying this episode sucks because it has no plot. It's utterly ridiculous!
