That doesn't sound pretentious at all... I like both hard scifi and comics. Don't follow Marvel or DC as much, because of the convoluted storylines and retcons, that are hard to keep up with, but graphic novels are definitely "with merit."
Before you dismiss all graphic novels and comics as for kids or illiterates, I suggest you check out the following: Watchmen/V for Vendetta by Alan Moore. Akira by Katsuhiro Otomo. Sandman by Neil Gaiman. Persepolis by Marjane Satrapi. And the current ongoing Star Wars comic series.
Grensback may be the "father of science fiction," but most of his works are regarded as pulpy throwaways of a bygone era, and Matheson is know more for his tv and the movies his books are based on than his written work. And, as much as I like Wells and Vernes and Poe and Bradbury, those are just gateway drugs to the better stuff. While still good, its the stuff they teach in school that everyone reads.
I like the deeper stuff. For my money, the Dune series is the best scifi series ever written and Philip K. **** being the best scifi author, in my opinion. Also, basically all of Heinlein's stuff is pretty damn good too, as well as Lovecraft.
