Re: The Classic Sci-FI Ultimate Collection
Well I finished off the last of the set yesterday and I'm satisfied.
Not going to delve into the OAR debate as both sides have good points.
I will say this:
Had these been Pan and Scan transfers of scope films I would have passed.
I can justify supporting OAR with the inclusion of
The Incredible Shrinking Man 
which is great to finally own.

Of the 4 open matte films, the two I care the most about (
Tarantula and
Monolith Monsters) looked fine framing wise to me.
In many instances the proper OAR on many films is not laid out in clear black and white and there are many compromises I've made over the years (over-matting on
Horror of Dracula, 2 cropped releases of
Apocalypse Now, the open matte Kubrick titles

, etc, etc, etc, so this wouldn't be the first.
Each of those examples are more severe compromises than this Sci-Fi set IMO.
For those passing on this set for the open matte issue, I'm not going to try and convince you otherwise or even state that you're wrong for doing so. To each their own.
