We watched last night and were surprised how good it was. My wife and I laughed a lot - just so many little jokes. While it probably wasn't THAT funny, for some reason the scene with the Jack and Rose doll where the doll broke and Jack sunk while Rose was floating on a piece of wood - holy crap - we actually lost it - we were laughing so hard I was crying. I think we were just kind of surprised by it, it was very funny, but then just got away from us. The kids were asking us why we were laughing so much, but didn't explain it. There were a lot of little jokes like that, but that one was really good.
It was also kind of amusing, not that we watch it that much, that there were the 4 main new Duck Tales actors. They even threw in a joke about that at the beginning when Bobby Moynihan was reading a Duck Tales comic. The Imperial March doorbell was really good. I also didn't even catch it but my wife pointed out that the doorbell itself was Captain America. A lot of good stuff like that.
