How to evaluate the movie Pirates of the Caribbean?

I fell in love with Captain Jack from the first movie, and then I have been chasing the Caribbean series. I have watched the first three movies many times, and every time I watch them, I feel excited and have more love for Captain Jack. However, I probably won't watch the fifth movie again. Captain Jack in my mind is a madman, who likes to flip his fingers and face all kinds of situations with ease. Despite the stormy artillery bombardment, he still ran with his light little steps. But! We! Captain Jack! He is not stupid! He is a pirate who has seen the world, but I think the fifth director let Jack's IQ go offline. Our captain Jack cherishes life, fears death, disobeys rules and reneges on his word, but he has a bottom line! Although he was betrayed at the end of the world, don't forget that he supported Elizabeth as the pirate leader! Maybe the purpose is not pure, this is Jack Sparrow, by hook or by crook. Finally, he remembered that he was a pirate, which may be his only bottom line.
