Is this worth watching?

Yes. If you half enjoyed the others, then you'll half enjoy this one as well. I laughed my ass off, and I think it is worth renting if you're looking for a fun movie. It has its moments, and the story was perfect for families to enjoy on father's day weekend when it was new in theaters. I didn't find it hard to follow either. There are good guys and bad guys and it's pretty straightforward. Out of all five films, Dead Men Tell No Tales is the shortest movie in the franchise.
