TV on DVD and Blu-ray remains very popular with more and more favorites being released. New TV reviews include: Star Trek: The Animated Series - featuring most of the Enterprise crew voicing their characters plus members of the original series' writing and production team, this is an imaginative collection of episodes with less constraints than the live-action material; Chicago Fire: Season Four - the program remains interesting but is already starting to feel a little tired with storylines from its first three years reworked with minor variations; and The Tonight Show starring Johnny Carson - The Vault Series - a dozen somewhat-randomly-selected yet uncut episodes from the ‘70s, these programs show the master conversationalist at work with a wide variety of stars.
