I just finished the Season 1 DVD set of The Rockford Files.
I thoroughly loved it! There is no one better than James Garner at conveying humor in dramatic situations.
I'm looking forward to getting the other seasons on DVD, as I didn't really watch the show as a kid. I got into it while watching a few eps when TV Land aired them at night a few years back.
Blooper Alert: in the episode "The Case is Closed" with Sharon Gless, Rockford is shown driving along in his usual gold Firebird. Then, suddenly, his Firebird is a newer model with square headlights instead of round ones! It happened twice in the ep. I guess they had to shoot additional road chase scenes. It probably would've worked if they'd only shown the car from the side and hadn't shown the front of the car.
I recommend the set highly! There's also an interview with James Garner as a bonus.
