Okay I bought the regular version today, because the extra $14 for a slipcover and a booklet is ridiculous since I never look at booklets and usually throw slips in the bin anyway...
My verdict on the transfer?
I've seen the film on VHS and DVD, but it has never looked so crystal clear, sharp and detailed. I heard mumblings that the original Terminator Blu-ray was as good as the film is ever gonna look due to the limited source elements, but oh boy were they wrong.
The 5.1 audio didn't even bother me. Sure I'd love the 2.0 option, but it ain't a deal-breaker.
Great purchase!
