Personally, I don't see the need for a debate. The concept of "Top" is pretty open-ended all by itself.
If we simply elaborate the name of the list to say HDC's:
Top personal favorites, or
Top drive-in flicks, or
Top date night horrors and so on, we'd all be clearer on the goal without the notion of some definitive 'top' that all of us must agree to.
I mean I'm a fan of Sharknado, but I've flushed things down my toilet that were better made. So 'best' movie? no, but personal picks? you betcha.
