i have to say though, its better than "THE CORE"
the beginning scene where Grint crashes his car on a driving test was a laughable start, but it went downhill with the slow road trip that followed.
the annoying parents also put me off, although other would say that they were there for comedy relief.
there's one stage when you see Gritn and Walter first meeting, and you wander if they're going to end up in bed together; UGH! that never happened thankfully.
i never stayed to see the end, i hope everyone else who saw it got a better time out of it than me.
