Destroy All Planets or Gamera vs. Outer Space Monster Viras.Oh boy the last film of the Mill Creek Sci-Fi Classic 50-Pack and it had to be another Gamera film - yippy, yippy! And this one is either truly awful or I'm just in a terrible mood - maybe a bit of both. A couple of the other Gamera films were kinda okay to watch but I did not like what I saw with this particular film - It just didn't have what the other films had to keep me interested.All of the Gamera films are crappy but this one is the worst of the batch I think. Oh well, not all of them can be good. That is what happens to franchises - they all tend to go down hill.1/10

Fourth Gamera film started the marked decline of quality in the series in this ridiculous entry that brings in the old plot device that plagued the later Godzilla sequels, that is alien invaders who plan on conquering the Earth by capturing Gamera and controlling it with an implant that forces it to attack Japan. Two Boy scouts on an outing befriend Gamera and somehow free him from the aliens' control, but then they unleash a giant squid-like monster called Viras to take over the attack. Can Gamera thwart their plans and save the Earth? Being partially set underwater can't save it, as this is far too childish to be believed.

I picked up this movie not too long ago with decent expectations. All I can say is that 60s Gamera was not 60s Godzilla. This movie came out the same year as "Destroy All monsters", and anybody who knows kaiju knows that's not even a debate. To say this film lacks the character, charm, art, graceful music and over all atmosphere of Honda's work is an understatement. Now, this film had many a problem that even for a giant monster fan were just hard to sit through.The camp is pretty horrendous, and the human characters are completely dismal. Same old annoying kids, in a world where youngsters are held hostage by aliens who then let them wander their ship which has a machine that can produce ANYTHING they desire. As far as idiotic plots, they could almost take the cake with this one. All along accompanied by a score I just do not care for.oh and did I mention that if you haven't seen "Gamera vs. Barugon" or "Gamera vs. Gyaos" you get to see like almost ten minute-each flashbacks of each of those films? These flashbacks go on for quite a bit of time, I suppose to give the appearance that this is a feature run-time flick. When I first saw it, I was surprised. About more than half of this movie's action sequences are stock-footage. For Godzilla's sake, don't use stock footage from a black-and-white movie in the full-on color one; someone's bound to notice you know? However, after 90% of the film being completely pointless and redundant, there is pretty entertaining fight at the end. Too bad it was too little too late. Viras is a squid-like alien kaiju, who I suppose to some extent would provide inspiration for Irys in the 1999 film "Gamera 3: Awakening of Irys", but it's a much simpler concept design. I tracked this film down pretty much for the adventure of watching all the Gamera movies, but by no means is this one of the best, not by far. "Gamera vs. Barugon" and "Gamera vs. Gyaos" are far better made, hell even "Gamera vs. Guiron" improves on this one. Watch if you dare!

The Gamera series takes a pretty substantial nosedive in quality with this regrettably cheap and plodding fourth entry. The plot is sound -- the big fire-breathing flying prehistoric turtle falls under the nefarious spell of evil space invaders and it's up to two mischievous boy scouts to free Gamera so he can successfully thwart the extraterrestrial menace -- but alas undermined by a conspicuously low budget (there's copious stock footage from previous Gamera films), a meandering narrative, too much goofy humor (the silly antics of the two boys wears really thin after a while), tacky and none too convincing (not so) special effects, slack direction by Noriaka Yuasa, and an often sluggish pace. That said, the theme song is quite catchy and rousing, the scenes of Gamera stomping on cities and destroying dams hit the thrilling mondo destructo spot something sweet, and Gamera's lively and exciting protracted climactic battle with an enormous one-eyed squid creature is loads of wacky fun to watch. Watchable, but overall nothing special.
