It's been a long time since I watched the film or listened to the soundtrack from beginning to end. I like the film, goofy and irreverent, with tons of memorable dialog. The soundtrack is not exactly John Williams level, but I feel it works for the film. The synth/synclavier sounds are cheesy and awful today; a proper orchestra would have made it sound much better:
Also, I think it would have been wise of Mark to team up with a "proper" soundtrack composer to iron out a couple of "creases". Mark's strong suit is writing melodic music, and I think indeed the melodies and motifs are good.
