Leonardo DiCaprio. I get huge, cringy ‘imposter syndrome’ vibes from him

Exact opposite feelings here, and I generally have a hard time suspending disbelief. I remember seeing The Basketball Diaries (this was before Titanic) and being blown away by his acting. I’d say this is a rare example of an actor being held back by good looks. A lot of folks have just not wanted to admit that this particular heartthrob has genuine talent. To contrast with, for example, Keanu, or Clooney.
