their lack of improvement over the years
(originally made this a comment but op deleted their post)
my biggest issue w/ them is how they've been idols for a while (six almost seven years), yet the "improvement" they've had since debut is marginal. if you look at their concert/comeback prep vids, it's almost always focusing on the choreo. enhypen are good dancers, that i'll admit, but their singing is barely serviceable. they sound fine in studio b/c they have autotune, vocal processing, and all that jazz to modify their voices - but whenever they attempt to sing live (like in encores), they sound subpar. even to an untrained ear, you can tell their technique isn't great.
i've said this once before, but if they're that far into their careers and haven't made any moves to improve on their own, then it just indicates that they don't want to. on i-land, jake said he wanted to become a kpop idol b/c he was impressed by bts' popularity. jay said he wanted to become an idol b/c he wanted to "be cool." ik goals change when you get older, but considering the lack of improvement, safe to say they're not in the industry for the artistic aspect, just the fame
