You take that back, Natty Ice kept me and the Sigma Nu bros in a happy spot for many a night back in the late '90s.
Molson Ice (Black Label Ice or just 'Black Ice' in Canada, 5.6% ABV if I recall aright) was good, and Icehouse (5.5%) had its moments (the latter is still available).
An abject failure was the short-lived Coors Artic [sic] Ice - another pretty bottle whose product inside didn't match it (looked and tasted like old wash water).
