Overall, this is not one of Spielberg's best, but it's hardly his worst. It's not really a plausible or realistic story, but that's okay. If you come to it treating it as a fantasy in a real world, you'll be just fine.
It's funny, quirky, and pretty charing, despite all of the ridiculous product placement. Even though the story is ludicrous, it is a funny concept to think about. I mean, a guy is trapped in an airport termina ldue to some nutty redtape and loopholes. There's a lot of material here for schtick, satire, and fun. ost of which is taken advantage of.
The performances are good. Hanks isn't the most credible foreginer, but he's still charming, classy, and funny. Stanley Tucci is great as the easily annoyed guy who trieds to do his best to keep Hanks' character from getting out of line and getting the best of him. Zeta Jones isn't bad, but maybe could have been a little better (just my opinion).
For a goofy but fun movie, this isn't too bad. It's kind of somewhere in the middle of Spielberg's filmography as far as quality goes, so take that as some sort of indication of whether or not you may like it. Saying that might not help, but you never know.
