Would having another season or two of the show have been a good idea? Or
do you think it had run its course?

It could have gone on for several more seasons. For this to happen, Ricky Segall would need to have left the show. Also, the music would need to have gotten a tad harder, as rock music did with the times. I'd also imagine that Laurie would have needed to get implants, as she was arguably the flattest lady on TV. Finally, their bus would need to have been replaced with a "greener" vehicle, like an electric van.

I hope that More season comes out on DVD
