“Mystery Science Theater” is back on Netflix, and it’s pretty much the same routine as before.

That is, some very amusing commentary on bad movies and some highly irritating set pieces involving space ships and evil aliens.

The series opens with a real oddity, the 1961 “Reptilicus.” It’s the only example I know of of that rarest of genres, the “Giant Monster Destroys City — in Denmark” movie.

Priceless observations on aquariums, armaments, acidic green slime, sweat, professors, electric eels, and cheese.

Three coils.
