Well, I do think they rushed Casablanca out when they should've been prepping a new 4K master...but "screwed up" is a bit harsh, considering the rave reviews that initial release got. Was it ideal? No. But it wasn't a complete botch-job, like...well, most of Universal's catalog output...
Hey...at least they gave Casablanca a honey of a new transfer this year, unlike the other endless repackages you mention.
I'll still take Warner over Universal any day, in terms of their catalog output.
