I wish I could say something really spectacular about this video, but it is at best mediocre. I have to give Jermay credit in that he didn't edit this thing down during the performance because he could have and we would have understood why. When the person you're performing the trick for on the video actually looks bored and keeps looking around as if to say, "When will this be over?", it's time to get another trick. That being said, this is an incredibly long video with a lot of teaching on it. Even though it's only one routine being taught, the teaching can be applied to other mentalism effects.
This is basically a three-phase effect that is supposed to supply perhaps 15-20 minutes of material for you. If you choose to do this, however, you are going to bore your group to tears unless they really find you fascinating or are simply really good friends. Jermay seems to go on forever before actually beginning the effect, and then unnecessarily explains to the spectator how the first letter of the cards form the words "THE SCAM". After talking about fake psychics, then mentioning "THE SCAM", the spectator is then supposed to believe you can read emotions and minds for real? Nope, not gonna happen.
Derren Brown has performed an effect very similar to this, but his pacing is much faster and it serves to streamline the whole thing. I'm not saying you should rush through the effect, but I AM saying you should "trim the fat" on the presentation given herein. Jermay has some nice ideas on cold reading that you can apply to other work if you want to.
I do like the fact that you get to involve another spectator during phase 2 so this becomes a little more interactive for others. Also, if you can somehow get phase 3 to work flawlessly for you, it ends with a bang. That's going to take some practice though, and you're going to miss it a bit in the beginning.
