Not sure about the Pern novels as a series, but I'd give it a chance. My choices ?
Kim Stanley Robinson's Red Mars etc.
Larry Niven's Ringworld
Alasdair Reynolds Revelation Space
Harry Harrison's The Stainless Steel Rat
The Stainless Steel Rat has been optioned frequently, but never escaped from Development Hell.
A few years back, I was visiting the Warner Bros. lot when I spotted the entire series sitting on a bookshelf in the Writer's Building, so clearly somebody took a stab at it at some point!
