The song begins with you playing along with the guitar rhythm identically (except for the muted notes). This means bass chords, and HO/PO chords. It's pretty cool for the intro.
But it's also the verse, where guitar deviates. It starts wearing itself down here due to the lack of variation. Then you get to the chorus, where again you play along with the guitarist, and again the guitar chart deviates while the bass keeps playing the same thing. However, the chorus rhythm does involve decent movement and a good HO/PO scale in there, so it's by no means bad.
Eventually a third rhythm (bridge?) is introduced and used one more time, which is good because this song probably would have gotten two-stars without it just due to lack of variation. This part is not particularly spectactular, but it's got some decent movement and more importantly variation, which this chart desperately needed.
This isn't going to amaze anyone new out there, but most RHCP fans can probably find it fairly enjoyable.
