Listened to it in the car with the kids on this vacation trip, probably making that about 25 times for me.
And I never get tired of it. To me, this is right up there with the Ramis-Murray "Groundhog Day" opus, with the added bonus of a great turn by Christopher Walken in a supporting role.
Yes, some usual gross Adam Sandler humor (excellent, really), but some classic life lessons - especially for anybody like myself who, both professionally and personally, lives a life of great anticipation. Just jumping to the good parts ruins all that.
Case in point: it is fascinating for me to look at Metsu and Abebu and Vonne Mei and Jerry on this trip and wonder what they'll all be like as adults. But what's the rush? The real enjoyment in that future world must be based on knowing them all along the way - putting in the hours, days, weeks, months and years as parents. There is no genuine payoff without putting in the effort.
All you have in this world is time and the opportunity to help others. The rest is all transitory and illusory.
