Does Pynchon Produce Only 'Masterworks'?

[Carvill, John]

<< Well my critique of VL's structure being unimaginitive has to do with comparing it to GR & V (VL's predecessors).  COL49's structure wasn't really inventive either, but its central themes were infinitely more developed than VL's. >>

I'm going way out on a limb here, obviously, but I would say Vineland strikes me as being more imaginatively structured than V., and maybe closer structure-wise to GR than is V. But obviously neither book can rival GR.
