A number of notable TV on DVD releases reviewed this week including: Avatar The Last Airbender - The Complete Book 1 Collection - the best of everything: - a highly entertaining animated television program and DVD set that makes the most of the technology; Slings & Arrows - Season 2 - mark this one down as the best TV series you've never seen... now go run out and get it; The Bob Newhart Show: The Complete Fourth Season - possibly the series finest year, one that Newhart himself acknowledges offers what are probably the two or three best-remembered episodes; Off to War: From Rural Arkansas to Iraq - even-handed and entertaining from start to finish, the ten-part series shows this complex, bitter conflict from a more personal perspective; The Old Grey Whistle Test, Vol. 3 - innovative and well filmed, touting solid listenable audio tracks and is as diverse as rock and roll programming gets; Forever Knight - The Trilogy, Part 3 - fans waited a long time for this final chapter, unfortunately the frustrations with it might outweigh the benefits.
