Why the low rating?

This has got to be one of the best puppet related kids TV shows ever. Ok, maybe I'm biased growing up in the 80's, but this seriously deserves better than a 6.9! It looked great, had interesting characters and story plots. I can only think of one other show that impressed me more...Anyone remember Star Fleet? Apparently Star Fleet is finally getting a release in the UK later this year. Anyway, I hope Terrahawks gets appreciated more here.
