This fourth season of “Seinfeld” has been called its breakthrough year, because it coincided with the show’s graduation from cult favorite to pop culture mainstay. If you’re a Seinfeld-head, this 24-episode box set is filled with (to borrow a network phrase) numerous must-see Seinfeld moments. At the same time, it’s still a little hard to imagine how such an edgy comedy ever became essential around-the-water-cooler-talk material. But against all odds, it did.

title: Sweet Valley High: The Complete First Season studio: Buena Vista Home Entertainment MPAA rating: NR starring: Brittany Daniel, Cynthia Daniel, Amarilis, Ryan James Bittle, Brock Burnett, Amy Danles, Bridget Flanery, Michael Perl, Harley Rodriguez TV broadcast year: 1994-1995 DVD release year: 2005 film rating: Three Stars sound/picture rating: Three Stars reviewed by: Mel Odom Based on Francine Pascal's bestselling books, "Sweet Valley High: The Complete First Season" gathers the episodes that brought the stories of the Wakefield twins to television. Identical twins Jessica and Elizabeth Wakefield, though resembling each other, are totally different in their attitudes toward life, friends, and goals. Jessica is all about hot guys and getting through school and stressful situations with the least amount of work on her part. On the flip side of the coin, Elizabeth is goal-driven and is always volunteering for causes and organizations. Joined by a gathering of friends and lightweight problems, except for the three-part kidnapping story at the end of the season, Jessica and Elizabeth get through ...

A TV series gets better and better, finally hits its stride so that practically every episode rocks, it show flashes of genuine genius – and it gets cancelled. In the case of “Angel,” this is particularly bewildering, as in its fifth season (2003-2004), the show was enjoying its best ratings ever, was doing great for the WB in its Wednesday night berth, had cut its budget (which makes its increased quality that much more notable) and had a slew of killer episodes. Ah, well, such are the mysteries of television. At least the episodes are now available on DVD, a good thing ...

Only 13 episodes long, it contains an unfortunate ratio of average (and even sub-average) material to good stuff. On the other hand, the good stuff here is very good indeed – some of it is in fact great. Factor in the multitude of episode-specific supplements in this eight-disc boxed set and you’ve got an unavoidable purchase for any fan of the show or even anyone who wants some resonant and original moments of TV.

The menus in particular are cool, starting out mostly on the bridge and including some fun animation that makes use of the various controls on the set. Also included are the good ol’ sound effects we’ve all come to know and love.
