Because... why not?

Who would've thought that an Elvis-like film vehicle for the Rat Pack would spawn one of the most successful film franchises more than 40 years later?

Nobody, least of all director Stephen Soderbergh, is ever likely to claim that the Ocean's Trilogy is some grand artistic achievement. It's a series of heist films driven more by the charismatic stars than by the story lines.

So why see Ocean's Thirteen? Well if you didn't particularly care for the previous films, there really isn't a reason to. If, however, you like the formula of the last two, you'll like this one too. In fact, Ocean's Thirteen is actually a tad better than the previous film, Ocean's Twelve in that that film just upped the ante by adding more heists, but this film instead doesn't try to add more heists, but downplays heists altogether. Yes, there is a diamond heist, but it really isn't the focus of the film - instead Danny Ocean's cohorts this time are out to avenge a wrong done to their friend Reuben by ruining the opening night of a casino owned by the hotel mogul that ripped Reuben off which precipitated a debilitating heart attack for poor Reuben.

As usual Ocean's plan is needlessly complicated, and overly reliant on luck, but really it's not the kind of film that's meant to be overly scrutinized either. You either like the slick, melodramatic, crime dramas, or you don't. If you do, you won't be disappointed with Ocean's Thirteen.
