(The book) raises a number of interesting arguments, most of which (the movie) ignores.

The only element in 21 that saves the film from being a dreary coming-of-age story grafted onto a two-hour commercial for the Las Vegas Visitors and Convention Bureau is Spacey.

O implaus?l terceiro ato praticamente arru? o que o filme vinha mostrando de interessante at?nt?

Too bad most of the performers can't seem to pull off the insane IQs they clearly do not have.

For a movie about high-stakes gambling, 21 settles for penny-ante dramatics.

Treating card playing as an exciting spectator sport rather than, say, about as thrilling as watching fishing for two hours, this offbeat cautionary tale warns all those impulsive casino-bound eggheads out there, that losers come in all IQ's.

This is a really stupid movie about such smart people... When they make references to Ferris Bueller and Swingers, it just feels desperate.

In real life gambling is exciting; on movie screens it generally is not.

For most of its length, 21 seems like a cautionary tale ... at least, until the whole point is negated by a tacked-on happy ending.

Fun and nothing else, but enough so that it's worth the while.
