Let’s say he’s flawed for the sake of the next movies, I’m ok with it. But the problem is still the same: there’s no actual threat I felt in TFA. […]If you felt he wasn’t a threat then the film makers did their job
Good for them. I guess it’s just not my kind of movie, then: I like movies with adventure and mystery, but different kind of tension and drama, it’s subjective.
I’m not sure what adventure and mystery have to do with a villain being a threat but you’re entitled to your opinion. If he completes his training by the time Episode VIII takes place he will be a monster. He showed a lot of potential in TFA
