There were several threads about it at the time so you're not alone, Blowout. I had nothing against Michael but he didn't really do much IMO. He seemed nice enough, but to be honest I didn't see him making it to the final anyway.
As for Spiral, I was a fan of his too, I thought he was quite entertaining! But sadly his moods weren't likely to go down well with the public.
All in all though I'm not too shocked that neither made it to the final, but that doesn't mean they were bad HMs. The 6 current HMs I expected to see there in all honesty. Plenty of the evicted HMs I reckon deserved a place too, but they've all come out learning a lot from the experience I guess....
