This movie was so... fantastic! It's a brilliant comeback for Wes Anderson after Darjeeling Limited, which I personally thought was a big flop and harkened much more to the heady earlier days of The Royal Tenenbaums and Life Aquatic with Steve Zissou.
I love Wes Anderson's humor because on the one hand it's a bit bizarre, but on the other, he says all those obvious things the rest of us just think in our heads, would never comment on, but can so readily identify with. His characters are stylish, awkward, obsessed, patient... I thought it was a hilarious study in human interactions and what makes people... ur.. animals, tick.
I also thought it was fantastic that this movie pays such a fabulous tribute to the original Roald Dahl book. I personally haven't read this one, so all the more brilliant to have a script based on a brilliant classic and keep it alive, rather than some stock-formula Hollywood story. Not that Wes Anderson could ever put out one of those!
Of course, since it's based on a kid's book, it seems suitable for all ages (but oh-so-wittily-entertaining for the grown-ups, too!) I think the kid and the adult in you both need to sit down with some popcorn and then let me know what you thought! ; )
