More good news: "Nova," "Justified," cable excess

The world seems to have an unlimited amount of television and a too-limited amount of really good television. So let's celebrate three bursts of good news -- two relating to shows tonight (Wednesday):

1) "Justified" has been renewed for a third season. This show (10 p.m. Wednesdays on FX) crackles with great characters and sharp dialog. Tonight's hour is a pretty good one, as two strong women -- a coal executive and a crime matriarch -- battle over mining rights.

2) "Nova" is rushing a terrific hour, "Japan's Killer Quakes," to the air, at 9 p.m. today on most PBS stations. This one arrived at the last minute, so the addition didn't get to all the papers in time. Here's the section I added to tonight's TV column:

TONIGHT'S MUST-SEE: “Nova,” 9 p.m.,
PBS (check local listings).

This science show usually spends months
on a report. Now it has rushed “Japan's Killer Quake.”

On one hand, we see the usual powerful
scenes, during and after the March 11 disaster. Alongside that,
however, scientists explain what happened and what steps could have been taken.

We learn why a 30-foot sea wall failed:
The tsunami waves were also 30 feet high – but the earthquake had
caused the wall to sink by at least three feet.

And we see startling sights, including
a saltwater lake, created on a mountain. It's a powerful hour.

3) And there's more coming up, especially on cable. Coming are three hugely ambitious series, each with a two-hour opener -- "Camelot" at 10 p.m. Friday on Starz, then both "The Killing" (AMC) and "The Borgias" (Showtime) at 9 p.m. Sunday. It should be a good weekend.
