No. The bar for "decent movie" doesn't move just because Nemesis and Into Darkness went way below where Insurrection did. The mere existence of Battlefield Earth doesn't magically make Wag The Dog any better.
At that point, I'd say it would be up to the Federation (or whatever interstellar civilization is visiting) to decide: Either they would begin developing the star system for their own use, or, they would make the system a preserve, in which case, if sapient life developed, they would no longer be able to decide to convert it back for their own development. Probably, at least in the case of the Federation, they would preserve it if sapient life appeared to be on the cusp of existing - if the monkeys are already banging the rocks together, so to speak.
Depends on what you mean by "advanced". You probably mean it the way we generally do - physically advanced. But if they were super *psychologically* and *sociologically* advanced, then perhaps they wouldn't approach dealing with a less advanced species in the way we might expect from our own less advanced perspective.![]()
What I'm saying is, that they would most likely blast us into oblivion just for the fun of it.
