Loose Discs

[beware]

There have probably been numerous threads on this issue already, but I wanted everyone's opinion on it.

I just got the LOTR EE boxset in the mail and part 1 disc on the 2nd film in the series was in the central location of the hub but not on it at all, just lose. Given a real glimpse sans defects but won't know until I play said disc all the way through. I have had loose discs before without issues, some with issues.

Wanted your take. What do you think of loose discs? Do you immediately feel deflated or when you get the time to watch the film and it has a glitch, you don't worry just simply return?
