Hero is back.

I loved cartoons when I was young. I did spend a lot of time watching TV [These sentences are mostly right, but you can save words by writing instead that  "I watched a lot of cartoons when I was young."] Then I grow up. I am still a fan of animated movies. Since there aren't any good Chinese movies, I usually see American animated movies instead. It's a pity, I think.

Then a few months ago, I was finally satisfied with a Chinese animated movie, whose name is titled "Hero is back " Hero is Back. (Rewording this sentence to omit the second comma makes it more natural. Movies and books are in italics or underlined). I grew up with the influence of the Four Masterpieces of China. One of them is "The Monkey King". The Money King has inspired "Hero is back" tells a story which is different from the original one. Although some of the details are the same, it turns out to be a brand new one story. [For logical continuity, I think you could put something like `Hero is Back is inspired by The Monkey King' after the first sentence of the paragraph instead of jumping into The Monkey King and then going back to Hero is Back. And then you can explain The Monkey King and how this new movie differs from it.]

I've never been so excited before. Jiang Liuer (the main character) is so cute, and he has the kindest heart which could melt a stone. And the Monkey King is not only the same one which that appears in the original book, but also a new character with a new personality.

It's a story of in which justice would [finally] defeat darkness finally. With a kind heart, everything could be is possible. With a mind of persistence persistent mind, nothing could be  is impossible (Great pair of sentences here. My suggestion strengthens the parallel you want to make by using the same structure for both sentences.). That reminds me of the old times when I was sitting in front of an old-fashioned television, watching my favorite cartoons. I think, it means a lot to me. Bbecause in this movie, justice never dies,. --just like every fairy tale has a happy ending (I joined the sentences because otherwise the last sentence is incomplete. Either: ``Because of this, that'' or ``That because of this''. ).
