Hopkins is miles better than Depp. Westworld had many outstanding actors led to demise by shitty writers.

why is acting and making your character believable not ok for movies?

Agree to disagree. The "original" trilogy was a fucking mess. The writers have even admitted as much on the DVD commentary: Curse of the Black Pearl was written as a stand-alone adventure that tied itself up nicely, but when it took off at the box office, Disney went, "So you guys are finishing the trilogy, right?" Making it a trilogy was a retroactive decision. And I think the later movies clearly suffer for it: way too much Captain Sparrow for an ensemble, shoveling in new characters to make the rest of the casts' continued involvement make sense, and ending the second on that cliffhanger was a wildly disappointing choice after how tight and self-contained Curse was.

Those two movies felt less like a continuing story and more like a theme park ride. But I guess that's an appropriate development.

They have exceptions to their statement. They didn't say they're guaranteed to be bad. They said, "I don't bother, unless...".

They kind of wrapped it all up with the trilogy. 4 and 5 were so forced and they sucked because of it.

If they want to reboot it, they need to just have a completely new cast of characters with their own personalities.
