Ignore the difficulty rating, this is back before Harmonix put much effort in differing guitar and bass levels. You'll see as I go on.
I'm going to open this by saying the first note you play that's actually part of a rhythm is around the minute and a half mark. That's not a good start.
The verse rhythm is decent, involving playing straight forths and a shuffle hammer-on from a lower fret. It's not good enough to hold my attention that long, though.
Especially when we get to the chorus, which is long sustains. After another repetition of those two, we get to the breakdown which is another part that's decent, with slow scales followed by sustains.
The problem is ultimately there's just way too much space where the bassist is doing nothing/minimal. It's not the worst bass in the game, but it's simply one I'd never want to play and can't see anyone wanting to either.
