Eloi - the Time Machine
saw another Hollywood remake from 2002, of H.G. Well's "The Time Machine" (almost not worth the review / comparison: the movie from 1960 was maybe more naive in special effects, but so much more consistent in how it was designed as also in dramaturgy - here iin 2002 there are many special effects and a hardly credible plot)
again, a paradise on the surface (the Eloi), based on horror underground (the Morlocks)....
(the same upper-lower theme as in Metropolis)
