What's bad about this movie?  It's called “Island of the Alive” for Christ's sake, what do you think?  Everything's bad!  Ok, like I said, the first ten minutes are actually pretty good, but after the courtroom scene, it's all downhill, and I mean ALL downhill.  In fact, it's almost enough to make me want to put the courtroom scene in the “bad” category, because it's such a cool little scene that it might trick the viewer into thinking that the movie is going to be good.  That's the cruelest trick of all.  I know it worked on me.  I thought, “cool, this movie is going to be good” and then spent the next 2 hours wanting to drive a rusty railroad spike through my head in protest of what I was forcing myself to watch.  While I admire Larry Cohen for continuing the storyline of his grimy little grindhouse masterpiece and tricking respectable viewers into watching the sequels, I have to be pissed at him because he tricked me, too.
 

Furthermore, doesn't it seem like the government would keep these babies in a lab and try to find a way to use them for warfare or something instead of setting them loose somewhere? Sure, the government wanted to pay lip service to the idea that they were being humane to these babies, but wouldn't it make more sense, fit better with the themes of the original movie, and be a cooler premise to have the government lie, say they were setting the babies free on an island, and then try to keep the creatures in a lab for experimental purposes?  What, did the filmmakers not have the budget to include a lab set in this sequel?  I know the whole premise of a mutant killer baby is dumb in the first place, but at least the original movie had the good sense to keep the action centered around a believable and recognizable setting: A cute suburban family excited
about the birth of their baby and then horrified when that baby turns out to be a monster.  The sequel took the premise out in left field a little, but it at least tried to keep the human element of the movie going strong by centering most of the action around another family shocked to suddenly have given life to a mutant baby. 

The third movie throws any stab at believability out the window and offers us this ridiculous premise where you'd have to be dropping acid to think it made any sense at all. The movie gets worse, though.  Oh boy does it get worse.  See, there's some mysterious disease killing off “the alive” (who, it has to be said, look so stupid in their fully grown incarnation that the special effects have to be seen to believed) so the monsters are trying to escape the island and...well, I can't really say more, as that would give away the end of the movie, but suffice it to say, scenes of some claymation and rubber puppet monster babies now in fully grown bodies hijacking a helicopter and then roaming the streets of a city make for a hilariously awful good time if you can manage to shut your brain off.  I couldn't do that, though, because the first movie in this dubious little trilogy was so good that with every awful plot twist I felt like the filmmakers were spitting on a classic.  I suppose if you can get over that and see the movie as the cheesy sleazefest that Larry Cohen meant it to be, you might enjoy yourself.
