The Nostalgia Critic2007

Oancitizen:
[on Russell Crowe's singing] When you get down to it, he's in tune. He knows how to phrase his melodies. But he's using a different style. He's trained in rock and folk, a subdued, naturalistic style. Musical theater is grand and stylized, and because of that, the nature of the aesthetic makes it easy to spot a faker.

Nostalgia Critic:
On top of that, Crowe likes to use his acting method of "If I act like I don't care, maybe I can trick you to care." But in this film, all the other actors seem to have that pesky mindframe of wanting to emote and convey actual emotion.
