Trust the writers, trust the writers. The melodramatic murder on the second-season premiere of “Friday Nights Lights” has everybody talking. It’s going to be interesting to see what happens to Tyra and Landry next. We don’t want our favorite show to turn into “One Tree Hill” in a small Texas town. One thing is certain: the storyline has given FNL sensational buzz in its effort  to capture a bigger audience. It was a terrific episode… great acting and writing. Didn’t see it? Go to NBC.com now and watch.
