The level of interest, for me, is the indignation about purported "cheating" when the rules have never been revealed. So far, no one actually knows. Tyler is openly saying to other houseguests that his feet left the disc and they have accepted it.
JC would manipulate this scandal to his advantage in no time, if it was a scandal.
Until the rules are available for this specific BB20 contest, there is no there there.
As far as Angela being dubbed over? Big deal. Houseguests aren't professional game show hosts. Maybe she sneezed so they did a do over later.
Much ado about nothing.
