I blame the TNG movies honestly, while some bits and pieces are good they ruined the series and if you haven't already you should read Michael Piller's book about writing for Insurrection, he basically exposes Patrick Stewart for being a(the?) major intellectual drive behind turning the movie away from the past TV experiences.

In general though I don't watch western TV much at all, maybe a dozen shows throughout my whole life so I can't say, but I definitely think much of TNG's personal relationships would be seen as boring and too professional these days.
