There are many ways to separate the wheat from the chaff. Various fan collectives offer thematically-related content, so if you like time travel or Q, you're bound to be satisfied — unless you dwell on what these packages miss, such as "Future's End". For my money, The Jean-Luc Picard Collection is the best value, as I prefer episodes that offer not an anomaly of the week, but significant, focused character development. "Tapestry", "Darmok", and "The Inner Light" are worth their weight in latinum, and with the former two both coming from season five, perhaps that is the series' best season. Other fifth-season episodes "I, Borg", "The Perfect Mate" (another Picard episode, and one which first unites Patrick Stewart with Famke Janssen, prior to their X-Men team-up), Spock's return in the two-part "Unification", and the first half of "Time's Arrow" supports this theory.

But only with the new, complete DVD collection can you get all the above along with gems like "The Best of Both Worlds", "Yesterday's Enterprise", and "Relics" — so if you have money to burn, take the good with the bad and splurge on all seven seasons (plus exclusive features and documentaries). But if you don't, then what season (or fan collective) do you recommend, and for what episodes?
