Well you're entitled to your opinion. I personally loved Boom Blox, and I don't drink. The graphics are certainly plain, but hardly "ugly as sin".

Was for me, wasn't for you. That's fine, but don't go telling everyone it's awful and avoid and declare it a public service. I don't go telling people to never play Mass Effect, Wario Land: Shake It, Echochrome, BioShock, Phantom Hourglass, and a few dozen well liked games just because it didn't click for me.
