My impressions might be best encapsulated by this exchange between Sam Waterston's and Elizabeth Rohm's characters. At the beginning of "Law and Order"'s 13th season, they discuss the incoming DA Arthur Branch (played by Thompson):
Jack McCoy: Nice fella.And I'll close with a quote from Thompson himself: "After two years in Washington, I often long for the realism and sincerity of Hollywood."
Serena Southerlyn: And his politics?
Jack McCoy: ...Nice fella.
