You are right about that, too. Not every movie needs to be Wrath of Khan, redux.
They could look to another episode of Star Trek for inspiration. Like The Devil In The Dark (seemingly hostile alien menacing a planet turns out to only be looking out for its young) or Shore Leave (beam down to a planet, and find unusual, or unexpected things going on there). They should be creative, and look to the original series itself for inspiration, not just rehash Wrath of Khan yet again
