I enjoyed playing this with my group very much; it was easily one of the most action-packed gaming nights we've ever had, and we will definitely be coming back for more. The game is very much about keeping an intense action pace by effectively penalizing distraction and down-time and prompting constant improv-style decision making. As long as you keep it in mind that the players are to be the protagonists of the next 'die-hard' movie, and that keeping things going is the name of the game, it will be a lot of fun. Our last session we played for 4 hours, but we all agreed that hadn't felt like more than 30 minutes.
The only complaint which I might make is that the 'Secrets' game mechanic is not explained clearly in the book, but carefully reading the examples cleared this up eventually, and it wound up proving to be a quite effective mechanic for keeping the ball rolling.
Also, some of the best design I've ever seen in a book like this.
