TV has been better than film since, oooh, around about the most recent fin de siècle.You know, he might be right. Over the last 10 years, the TV series as a genre has really started to get to grips with the arc of a series, as opposed to the arc of an episode. I'd probably add shows like The Sopranos and Six Feet Under to The Wire, as highlights.
If you had to point at notable trends in film over the same period, you'd probably look at the success of effects-based films, particularly the big-budget fantasy adaptations (LOTR, Harry Potter, new Star Wars), and the return of the superhero genre (Spidey, X-men, Batman). I can't think of many notable other dramatic developments - renewed interest in epics, perhaps?
