General thoughts:After the popularity of the internet musical, a soundtrack was to be expected. The whole album is very short (25 minutes), so don't expect hours and hours of music (unless you like it enough to listen to it over and over).
Neil Patrick Harris has a great voice here. Nathan Fillion does too, but since his character is such a jerk, it's hard to get excited about the parts that feature him. I don't much like Felicia Day's parts as much.
All in all, if you liked the film (or whatever you'd like to call it), then buy this.
