Really? I would be shocked if Lynch WEREN'T an influence on Tarantino. Lynch isn't making the same kinds of movies as Tarantino these days, but Blue Velvet is very much in the same vein. BV is essentially a investigative thriller told in a funky way. In fact, QT's True Romance is very similar to BV - they both are about innocent young men who fancy themselves resourceful and end up in over their heads. BV is also very much tied in with American pop culture like QT's work, and both directors seem to embrace pop culture while simultaneously criticizing it.
