NBC's latest summer reality entry "The Law Firm" had a ho-hum start Thursday in what remains primetime's toughest time slot, even during the summer repeat slumber. Executive produced by David E. Kelley, "Law Firm," an elimination style show revolving around a group of a dozen lawyers challenged to impress attorney-to-the-stars Roy Black with their barrister skills, opened at 9 p.m. to 5.1 million viewers and 1.9 rating/6 share in the adults 18-49 demographic, according to preliminary estimates from Nielsen Media Research. Crime Scene Investigation remained the dynamo of the night, though it did slip a few notches from its recent repeat performance levels to finish out with 13.1 million viewers and 4.1/13 in adults 18-49.
