The Flintstones Meet the Jetsons One of the best crossovers nobody is talking about anymore is a movie created by Hanna Barbera for TV in the 80s. When I was a child this movie exploded my mind because I had grown up watching both shows. I know that nowadays people think that the Marvel movies have the best crossovers ever made; however I don't agree with that, because the quality of those movies is irregular. I prefer watching a crossover between two iconic shows that are totally opposite (Don't really need more words but could say 'from one another') The main plot of this movie starts when the Jetsons travel back in time and they end up meeting the Flintstones. I loved how both groups in spite of their differences could / were able to start a great friendship almost immediately. My level of excitement was really high; I watched that movie several times. This crossover didn't happen again, at least in animation, which is really sad and very disappointing. However, I think that is what makes this crossover very unique and special. I want to be clear, this movie is not a masterpiece. In fact I might say that its plot is very simple, but in my mind it is the best crossover ever made. I'm a simple guy with simple tastes, I think that a bowl full of cereal and movie like this one was everything I needed to be happy in my childhood. Nowadays it is very difficult to achieve this kind of simple satisfaction. We have a lot of Marvel movies every year, but the feeling is not the same. I'm not saying that Marvel movies are bad. I'm saying that as a child my sense of enjoyment was different. Really good. However, there are a lot of run-on sentences. You should master when a full stop (period) is needed. You might also study the use of the semicolon, and when a comma is necessary. Most of the time you don't really need the semicolon, because periods will do.
