Decent story with a phoned in script.

Rating: 5/10 (8 September 2017)

It's watchable in a mild sort of way. It's not terrible. There's just too many problems.
1. The elephant in the room is that the dialog is really bland. I was getting into it until there's a part near the beginning(not a spoiler) where this kid drops a bunch of leaflets for Jack sparrows capture, This prisoner picks one up and says in the most monotone line ever "Jack sparrow. Hes dead buried on" etc etc. Not in a mischievous or or foretelling way just "hey jacks at such and such". There's slick line in Deadpool where this bartender says "You should go see want he wants..might further the plot.". It's meant as an in joke. However thats 90% of the lines in this movie. There's a very occasional quip but most of the lines are people saying lines indicating whatever furthers the plot. Worse in some cases even the delivery is phoned in. Thats a directorial problem.
2. It's too much again. There's a villain a maguffin and about 5 or 6 nonsense subplots. It's tiresome and they work they put into tying up each one takes way too long.
3. The villain wasn't empathetic or interesting or even fun. The first film was a pretty fun, straight forward ordeal and the villain was likable. In the last two watchable ones, The dads plight emotional and Davy Jones was well done and empathetic. This one has an angry ghost who's a jerk with a yawner backstory. He was well acted just boring. This leaves the entire enterprise lacking in that Epic tone the original trilogy was going for. The whole thing reeks of people being paid to make a movie and there's no soul to it.
All that said it's watchable. The acting is mostly fine and the special effects are nice. It also moves a nice clip. I remember the 4th film losing me at this chase scene early on that goes on for like 10 minutes with no payoff. If I watched the rest of it I can't even remember. This one I suspect I'll at least be recall the major points a year from now.
I would only recommend this if you've sincerely run out of things to watch and are at least a couple beers in.
