How Important Is The Rewatchability Factor?

[Professor Echo]

When you are contemplating buys, how important is the potential Rewatchability Factor for titles? I'm sure some people buy a title just to see the movie and then quickly flip it, but others, like me, give serious consideration before purchasing to whether or not there seems to be enough appeal for more than one watch. Even with blind buys I do some (hopefully) spoiler free research and try my best to gauge whether there will be repeat value in a title or not. I just can't fathom building a dusty collection of a lot of Blus I'll only watch once.

How about you? Do you make a conscious effort to gauge this when deciding to buy or not buy?
