I agree with your assessment. It is good, but the first one was better. I think that NT-TBOS was a setup for a third movie.
I too saw it on Christmas Eve! I am not as kind as you two reviewers. It was just okay. Much too repetitive from the first outing, too many plot holes and logical discrepancies, and worst of all, too much standing around talking. I loved the first one and watch it repeatedly on DVD. You can bet that one time was enough for the second one.
