Galaxy of Terror is great sleazy low-budget Alien rip-off fun. The blu is a revelation, it looks twice as good as I ever thought it could. After years of a way too dark full screen download, then a couple years with what I thought was a beautiful anamorphic dvd rip from Italy. The blu crushes them both.
Piranha also looks great on blu, but probably not as substantial and upgrade as Galaxy is. I also have Humanoids and Forbidden World, they did a great job on all of them. I think Galaxy stands out so much more for me as all old transfers looked like shit one way or another. I can see things on the blu I thought were always hidden in shadow, the maggot scene stands out most of all for this.
