This movie was divided into three parts for me. First there were the set-up scenes: Gary arranging the reunion tour and providing background of the five friends. It was fairly predictable and I found it almost impossible to overcome my dislike for the Gary character. It was only because I was slightly distracted by something else that I kept watching it. Then at about the 35-40 minute mark, it got better. There were action scenes, of course, but even the humor seemed to pick up the pace, and there was a little character development and growth. It was fun viewing for a long time.
Then there was the third section (again, for me anyway) when the plot is wrapped up at such an alarming speed so as to result in an anti-climax. And that is followed by a rather lackluster narration by one of the characters stating what had happened to everyone and explaining the ending that the movie had covered so scantly.
So I can’t say I regret watching it, but I probably wouldn’t watch it again if the opportunity arises.
