Although it was a low-budget affair airing on the basic-cable USA channel, Swamp Thing (1990 - 1993) actually features a very strong, very lovely introductory montage, one that captures well the essence of the "dark" superhero series.
The opening montage commences with misty, dark views of what could be another planet all together: the swamp.
In virtually all the shots featuring views of the swamp (save for the moment that the title comes up...), the camera is in motion, suggesting that we are prowling or moving about in this world.
We are in motion, traveling, seeing the sights of this strange terrain...
Below, the live-action version of the Swamp Thing opening montage, from later in the series' run.
