I know plenty of people who are unmoved by HALLOWEEN, so you're not alone. I happen to think it's a masterpiece, but other opinions exist.
HALLOWEEN's one of those movies that has just never looked consistent in the DVD/Blu-ray era in terms of the color timing. Even versions supposedly approved by Dean Cundey, the cinematographer, vary wildly. The new 4K release from Scream Factory is supposedly very good.
