The first thing you'll notice is that, like the rest of the releases in the series so far, each and every one of the episodes in this set has a commentary track from those involved in making the show. While this may sound like overkill, most of these tracks are not only very interesting, but also quite funny. The crew members involved in making the show obviously have a lot of fun with their work and enjoy the working relationships that they have together as it shows in each one of these track. They prove to be not only interesting in terms of the animation and background information on the show, but also in terms of trivia and little references and anecdotes littered throughout the series that you might not necessarily pick up on just watching the show regularly.

I'm going to break the extra features for this release down by what's included relating to which episode on which disc. Ready? Good. Here we go…

Who Shot Mr. Burns? Part 1:One deleted scene: Homer swears so loud that the Church organ can barely cover it up. Next up is a commentary track from David Mirkin, Bill Oakley, Josh Weinstein and Jeffrey Lynch. James L. Brooks also provides a very quick one-minute audio introduction to this episode, stressing its importance at the time it originally aired. Also on this episode are four alternate language tracks, so aside from the English, French and Spanish audio options, you can also watch the episode in Parisian French, Castillion Spanish, Russian and Czech if you so desire. Next up for this episode is the twenty one minute special, Springfield's Most Wanted that Fox aired way back when to generate hype for this episode. Done in the familiar style of America's Most Wanted this is a fun spotlight on the show that is hosted by John Walsh who does a fine job of pretending to be very serious as the tabloid style news show tries to figure out just who it was that shot Mr. Burns that fateful day in Springfield.

Now, in addition to being able to view the deleted scenes in the episodes in which they were originally designed to be in, on the fourth disc there's a Deleted Scenes Reel that allows you to check out all of the scenes with optional commentary from David Mirkin who explains the reasoning behind the decisions to axe all of this material from the broadcast versions of the episodes in this set. Combined, this segment runs for twenty eight minutes and it's an interesting way of getting a look behind the scenes as far as the editing of the show is concerned.

Rounding out the extras on the fourth disc are two Church's Chicken commercials featuring Simpsons characters, a 1-800-Collect commercial, and a two minute new segment on a Simpsons plane that was made by Western Pacific Airlines who designed it to look like it belonged in the show. Oddly enough, Matt Groening and David Mirkin provide an optional commentary for this segment as well.

The copy of the set that Fox sent for review did not contain a booklet inside, though there was a spot where one could be housed and I'm going to go out on a limb here and assume that retail versions of the set will in fact include a booklet inside the packaging alongside the discs themselves.

On a semi-related note, I have mixed emotions about the packaging that Fox has chosen for this release. The good news is that the four discs in the set come inside a keen plastic replica of Homer's giant yellow head. The bad news is that this head doesn't really line up properly on the shelf next to the first five seasons packaging, and it doesn't even remotely resemble it either. While from a creative aspect this set looks great, from a practical aspect and for those of us anal enough to complain about such things, the sets now look kind of odd beside each other. Add to that the fact that storing a rounded head shaped set is trickier than storing a rectangular box and there's the potential that the packaging could become damaged fairly easily as the plastic used to house the discs (which are each inside a sort of four sided keep case binder inside Homer – they're not lose) isn't the sturdiest I've ever seen. The packaging is an interesting experiment, though I'm not entirely sure that it was a completely successful one. The good news is that Fox is allowing fans to send in for a mail in replacement case that fits the format of the earlier season releases, proving that every once in a while you can have your cake and eat it too.

One of the strongest seasons in the history of the long running fan favorite series gets a superb release from Fox. While the packaging has it's pros and cons, the episodes look and sound very good and the supplements are not only plentiful, but also a lot of fun. The Simpsons – The Complete Sixth Season deserves the DVD Talk Collector's Series stamp of approval!
