Yeeeaaah...buy it for the pictures, I guess. the 'How To' elements were pretty restricted by the publisher's previous templates. Really could have done with a few extra steps in between, I think. And...it doesn't appear to have been edited that stringently. And this is the 2nd edition too. Ho-hum.
I saw it at Botcon for $5 from IDW and still couldnt bring myself to pick it up. It seems like the ones in the titan comics to go from here are some circles in roughly a humanoid shape to heres a fully rendered drawing of Optimus Prime.
