No. Absolutely not.
Buy the first three. They are gold. And if you're not in the money, just get volume 1 and 3. Even the performance reels are a joy to watch. All together they make up a mini street magic special.
The new ones.... they really suck. Even Garcia himself sucks. He's boring. Lacks the enthusiasm and energy he had in the first set. Even in explanation, sometimes he speaks rigidly and scripted with this dead look like he's pretending to be one of the Buck twins. Many of the effects don't have audience performances. It looks like they tried to give the performances some of the feel of the first set, with the whole "road trip across texas!" thing, but they just fail. They do several similar shots (hip level shot of a location or DG walking) that are slightly reminiscent but its just dead. And the actual audience performances were boring at best, except for the iCard performance.
Now, I only have 1-3 and 4 and 6. Maybe somehow volume 5 is sheer genius, but I doubt it. Seems like Garcia has been wrung dry since the original DGP came out. For me, the only seriously good thing off the new set was "On the Rocks" (looks REAL) and the iphone/ipod magic. Other notable tricks were POP! and party perception, which I've not tried, but looks like it has promise.
