Roeper is the same guy who said Arnold deserved an Oscar nomination for T3. I don't value his opinion much.
Also the less-than-stellar reviews for Jack don't worry me too much. I have friends that worked on Jack and they told me it was obvious Singer was just doing it for the paycheck. With X-men however, you can tell Bryan is very excited.
Is this the excuse for the reason why its flopped? "Oh his heart just wasn't in it".
If I were studio investing money in a film then I'd be worried about director who's heart just isn't in it.
