Here's the objective and factual truth about the POTC franchise...in my opinion.
COTBP: Fun, creative, likable, and charming, with plenty of great gags and well-choreographed scenes of swordfighting and swashbuckling. It's the perfect movie for when you want to kill an afternoon.
DMC: Stupid, nonsensical, needlessly complicated, and overlong, but there's still plenty to appreciate. Davy Jones is entertaining, the wheel fight and the Kraken scenes are incredible, and there's still Captain Jack and Barbossa doing what they do best. Not great, or even good, but you can still get some enjoyment out of it.
AWE: I haven't seen this movie since it first came out, so maybe there's a bias there, but I remember almost nothing from this movie, outside of the opening, which is far too needlessly dark for a fuckin' POTC movie, and a couple of random scenes here and there. Maybe if I rewatch it I might get something out of it, but I'll probably just end up strongly disliking it.
OST: They tried to scale down, but it once again is overlong, and needlessly complicated. There are some select scenes that are enjoyable, like the mermaid scene, and Jack leaving Angelica on the island, and Angelica herself is a likable character, but most of it is pretty boring and forgettable. It's a shame since they treated the movie like a soft reboot. Hopefully next year's soft reboot will be better and bring Captain Jack back to his former glory.
