Query: Disapointing Read

I loved Angels and Demons and The Da Vinci Code, so I thought I'd try one of Brown's earlier works. I was sorely disapoointed, as you can tell from my title. It lacked the flash and panache of his works already mentioned. Too much invention, rifles that fire ice and sand bullets, ships capable of near impossible speeds, and of course "black" helicopters firing missles at the FDR Memorial? Uh uh, I didn't buy it, but I did finish it, mostly because it was a fast read, and I didn't feel like I was devoting too much time to a mediocre book. Not that they can all be great, maybe I should have started at the beginning and worked my up, might have been pleasently surprised.
