With a 18 month old, the wife and I watch around 4-5 movies a week, sometimes more if there are good new releases out. We don't have a dedicated HT, but both our living room (58" Samsung 8000 series plasma, Paradigm on walls, and SVS PB12 Plus/2) and bedroom (61" Samsung LED DLP, Polk RTi12s, sub TBD) have decent setups in which we like to enjoy good movies and cartoons for the little one.
