It's sad to see so many good titles get ruined because of this

They do if they retcon things that happened in the good installments, like MSG4 explaining all the cool and unexplained stuff from the previous three by saying "nanomachines did it" except the one thing that would have made sense to be nanomachines, which turned out to be a case self-hypnosis.

They should have spent the budget on something that was original and took a risk. We can watch a shitty reboot or a shitty original - and some of those original movies that are panned as not good at least have a shot at maybe becoming a cult classic or a fan fave.
