LOS ANGELES -- After so many years -- and episode re-watches -- could there BE anything left to learn about "Friends"? As the highly-anticipated, almost two-hour reunion special for HBO Max shows (and with apologies to Matthew Perry for continuing to borrow his lines), "Yes, yes, a thousand times, yes." One thing that we didn't need to learn (because we already knew it) was just how truly there these six characters were for the audience. In the 1990s and early-aughts, the cast of "Friends" provided hours of joy -- first just on Thursday nights when new episodes aired, but soon enough five nights a week in syndication.
