I thought it might be nice to submit good reviews for season 3 found on the net.
Here's one I found.
Season 3 of Gilligan's Island finds those seven stranded castaways still marooned on a tropical island, still making the best of things (it's an uphill climb!), and still seeking out any and all methods of escape. The only change during the third season is a cosmetic one; now, most of the 30 episodes open with a pre-credits "teaser," setting up the episode's premise -- and of course, re-introducing Gilligan (Bob Denver), the Skipper (Alan Hale Jr.), Mr. and Mrs. Howell (Jim Backus, Natalie Schafer), Ginger (Tina Louise), Mary Ann (Dawn Wells), and the Professor (Russell Johnson). Fans of the series consider this season the best ever, with some truly unforgettable episodes. Among these are "All About Eva," featuring Tina Louise in a dual role as Ginger and her drab lookalike Eva Grubb, and "The Second Ginger Grant," in which a bump on the head causes Mary Ann to take on the voice and personality of Ginger (a true tour de force for the talented Dawn Wells). Perhaps the best episode of the lot is "The Producer," guest-starring Phil Silvers as Hollywood mogul Harold Hecuba, who takes over production of the castaway's own musical version of Hamlet -- and plays all the parts in the process! Other noteworthy guest performers this season include John McGiver as eccentric butterfly collector Lord Waterford, Rory Calhoun as crazed big-game hunter Jonathan Kincaid, Strother Martin as befuddled "take-a-dare" game contestant George Barkley, Don Rickles as inept kidnapper Norbert Wiley, and Vito Scotti in a return engagement as mad scientist Dr. Boris Balinkoff.

That is a good review. That whole review itself really explains Season 3 of GI.

It is so hard to find a review of someone who has actually watched the DVD's. A lot of them are from the one source and haven't even seen them yet.
Here's another good review from someone who obviously seen the DVD's.

A lot of television shows have been released on DVD, but most are newer programs, though some classic television is starting to surface. Gilligan's Island is a welcome addition to that list, as the show is a blast to watch and has legions of loyal fans. I can understand why some folks think that syndication makes this kind of set useless, but let's be honest, who wants to live their life around a viewing schedule? I'd much rather sit down at my leisure and view whatever episodes I wish, in whatever order I desire. In any event, Gilligan's Island has become a cultural icon, even though it wasn't an instant success. Bob Denver's trademark Gilligan drives this show, but the rest of the cast is just as important. I mean, Ginger and Mary Ann have been fantasy fodder since the show debuted, a trend which still continues. As with all shows, the issue here is how often can the series be rewatched. That isn't much of an issue here however, as the show still performs well in the syndicated scene. In other words, fans will never tire of the show's style and of course, Gilligan's endless antics. This third season release from Warner is excellent, as the episodes look superb and the supplements are worthwhile. So if you want to return to the island, be sure to grab Gilligan's Island: The Complete Third Season.

Video
The episodes are presented in full frame, as intended. I knew the episodes would look good, but I expected some obvious flaws to surface. I thought grain and debris would be evident, while the visuals would have an overall soft texture. As it turns out, I underestimated Warner this time, as these episodes look almost brand new. The prints are in great condition, with minimal grain and debris is light at worst. I have to assume some restoration work was done, unless Warner found some prints that were untouched. The image is never soft either, so detail is high throughout and the visuals have a crisp presence. I have to admit, I never thought this show could look this good, so I commend Warner's work on this release.

Audio
Aside from the well known title theme, the audio in this show is reserved and follows a simple comedic system. You have a laugh track present, which is bothersome at times, but aside from that, I have no real complaints. The audio is mono, which means depth is limited and such, but with material, dynamic sound isn't needed. The music sounds clean, while the assorted sound effects, such as coconut bonks, come across in fine fashion. No worries in terms of dialogue either, as all the corny one-liners and other vocals are well handled. So no dialogue is washed out or muffled, which means given the materials, we couldn't ask for much more. This release also includes subtitles in English, Spanish, and French.

Extras
There aren’t a whole lot of extras, but a rather inviting commentary on episode 4 (The Producers) is a welcome addition. The episode is considered one of the best in the series and Schwartz offers up a good track here. There is also an introduction (just like the second season) to the set and a look at the impact of the show and its relation in the pop culture status of America. It’s hard to believe that the show only ran for three seasons, but the good news, little buddies, is that they’re all available on DVD!
