I am mixed on that.

For me there are 2 issues

(1) I read the book. it was awesome. If the movie fails to deliver that awesomeness then it's really upsetting as it's ruining something great for everyone that didn't read the book / see the original. They're unlikely to go check the original. They're more likely to just think "That was dumb".

(2) When they change things so much that they arguably should not have used the name.

Why choose some existing fictional world/characters just to shit on them and make it something else? If you wanted to make something else, then pick a new name, make your own IP.

I actually really liked the live action adaptation of Cowboy Bebop, and was disappointed at it's cancellation.

Unpopular opinion amongst those who grew up on the anime, but I was late to the anime so my childhood-integrity isn't dependent upon requiring a faithful one to one retelling (or whatever would satisfy those folks - possibly nothing).

I enjoyed the "Hollywood" Ghost in the Shell as a stand-alone 'thing', unrelated to the manga / anime. The ending is quite on the nose; ultra-formulaic where formulaic has no place.
