GHOSTBUSTERS had great film grain retainment albiet slightly upped contrast. I've only seen screenshots and it's a must buy for me.
Stay away from Peter Benchley's THE BEAST.

EDIT: WHAT THE SHIT?! STARGATE (Lionsgate, second corrected subtitled release, BD25/MPEG2) looked terrible the other day! No film grain from what I could tell. Going in the sell off bin and gonna buy the 15th Anniversary Edition Blu-ray.
