The view of charisma that your talking about is narrow. Charisma doesn't just mean fun loving characters or having snappy and charming dialogue. That's not what I'm talking about at all. Charisma is having a presence that draws people to you. Some kind of magnetism.
Ryan Gosling has played a good amount of roles in movies like Blade Runner 2049, Lars and the Real Girl, Drive where he was for the most part a muted, stoic, and/or understated character. But still you're drawn to him because he has charisma and a presence.
And even people closer to Lerman's age like Timothée Chalamet, Lakeith Stanfeld, Dylan O Brien, Ashton Sanders, Lucas Hedges, Kaitlyn Dever, Saoirse Ronan, Leitia Wright, Awkwafina, Kelvin Harrison jr have a presence and charisma to them. Whether they're in a lively role or not
Lerman showed that in Meet Bill and Fury but that's only 2 roles in like 15 years. I never have seen Sidney Hall so I'll take your word for it. I heard very mixed things.
