Old Dogs trailer.... More like Old Hat ?

This looks kind of like a rehashing of Three Men and A Baby. I just kept thinking to myself while watching this trailer...why is Travolta and Williams doing this ? Must have been a good pay day. I know you can't take everything just from a trailer, but this clearly looks like the two are mailing it in. Remember when Robin Williams did top notch work with great writers and filmmakers ? Oscar nominated fare. He looks like he is accepting every offer that comes his way. And could Seth Green look more out of place with these guys ?
