Some great TV on DVD releases reviewed this week including: Threshold - The Complete Series - a series chock full of potential (but unfortunately canceled) episodes seem to stand better on their own than as a complete series; Survivor Palau - The Complete Season - while not one of the very best of Survivor seasons it's still worth watching; Invasion - The Complete Series - with an extremely slow start (it takes 8 episodes to get going) its a show which rewards only the patient; Sealab 2021 - Season 4 - a series who had a great run, survived losing its lead character and helped make Cartoon Network's Adult Swim the phenomenon it is today; La Femme Nikita - The Complete Fourth Season - if you find Alias intriguing, 24 appealing, and like watching shows where the writing and mood are more important than car crashes or special effects, you're going to really enjoy this show.
