This review is for the episodes in this set, not the set itself (although the artwork looks spiffy!)
211- First Spaceship on Venus A controversial add among fans, but this episode unnecessarily gets a bad rap. The basic movie is about a multinational space expedition to Venus (a theme in a least of couple of later MST3K experiments). Goofy of course, and funny, but the host segments are fun (others disagree, but who cares?) The Brain's own "Amazing Colossal Episode Guide" The Mystery Science Theater 3000 : Amazing Colossal Episode Guide indicate that this wasn't one of their favorites, but they have said that about lots of MST3K episodes that others enjoy. Your mileage, of course, may vary but any early MST3K is worth a look.
706- Laserblast This was the final experiment of Season 7, and indeed the era of hours upon hours of MST3K as filler on Comedy Central. It's the Cadillac of this set, and almost worth the price of admission. The movie is priceless - an androgynous, hopelessly attractive loner finds an arm-sleeve laser gun in the desert, and is quickly seduced by its power. Seduced? No, he's turned into an alien. After tasting the fruits of his forbidden power, our hero goes on a rampage. He doesn't rob banks or blast bad guys, he goes after Eddie Deezen, cast out of type as a annoying geek (and kind of a bully, too.) The host segments involve the end of the SOL's funding, with Pearl pulling the literal plug. Our heroes go off to the void, and Dr. Forrester finds a 2001-esqu fate. A keeper, and I'm delighted to find this more or less permanently preserved on DVD at last!
904- Werewolf (aka "Wahr-wilf"). One of the better episodes from the unfortunately truncated Season 9 - it stars, well someone, with an unfortunate encounter with the teeth of a wolf skull involving stitches. It also stars perennial B-movie villain Richard Lynch, with a low-rent cameo from Joe Estevez as a sun-addled native archaeologist day laborer. Check out the impossibly predictable twist ending. The host segments are about as good as MST3K has ever generated - Mike attempts escape (and is quickly detected by the otherwise incompetent Pearl, Professor Bobo, and Brain Guy). There's even a nifty song, "Where O Werewolf".
1004- Future War By this time the show was on the way out the door, but in the last couple of years MST3K featured some really cheesy bad 1990s-era monster movies. This one is actually not as bad as many, if you can get past the rubber dinosaurs. (Plot? Oh yeah, a man from the future visits a la Terminator, quickly followed by man-eating dinosaurs - or something). The host segments are serviceable, involving dropping LSD, kick boxing, and making fun of someone's facial-deforming illness (never said MST3K was a great family show).
I had the pleasure of interviewing the cinematographer of "Future War", and his attitude towards the MST3K treatment of his film was delightful. The crew of "Future War understand MST3K, and they have a terrific sense of humor. This is a better episode than most, and it's great to have it on immortal DVD.
On balance, there are some unusual choices for this box set, but it sounds like Shout Factory is on the right track. Looking forward to many future box sets.
