There's little question as to which local station provides the most solid, least sensationalistic, most in-depth news product -- it's KHOU on Channel 11. The station fields a solid team of veteran reporters, not to mention Mister Hurricane himself, Dr. Neil Frank. And as the other big stations in town head for the ratings crack of stripper and hooker investigations, KHOU has led the way in documenting the pathetic slapstick of the Houston Police Department's DNA lab. This being local TV news, there's apparently no way to entirely escape the occasional inane feature, but Channel 11 limits the silliness better than the rest. The bigger question is, Can KHOU survive? As far as ratings go, it seems that Houstonians prefer the blaring, skin-deep glitz of its competitors. We can only hope viewers eventually swear off the junk food and go for something more substantive.
