He will make star in amazement and laugh. You wonder if some of his lines were meant to be said the way he says them and think about how weird he makes captain jack. He alone is a good reason to watch it.
There is only two reasons to watch this film... 1) if you are so utterly bored, and 2) if you are a fan of Orlando Bloom or Johnny Depp. The movie never should of been made. The worst part is the end, it sets itself up so that some moron could very well continue the Pirates saga if they had enough cash to throw around.
If you have never seen the previous Pirates film this movie would seem disjointed at best. Its clearly set up as filler for the 1st and last movies. It is far better than the 3rd movie in the series, however not as good as the first. Main reasons to see the film are if you are like me, a fan of Johnny Depp and Orlando Bloom. They both really carried the film and are imho, the best actors of all 3 films in this trilogy.
