Good movie, but not exceptional. Worth a watch definitely, but couldn't see what was so cult - ish about it.
Its set in a world where people can enter each others dream worlds. One man, with a chip on his shoulder and a ghoul in his sunconsious, is given a job to do in this dream world, who then assembles a team to do it, and how they go about doing it. A sort of sci -fi thriller you can say.
As for the concept itself, I don't think its particularly new - nn and I looked at each other , said star trek, and sniggered. There was a voyager episode, which had exactly the same group-lucid dreaming, right down to the totem part. There are lots of movies, which pick similar kind of themes, so I'd say it wasn't totally sensational.
Next for the execution part, again, if seen from a taut thriller kind of view, again good but not sensational, in fact it got to be a bit of a drag in parts where all you saw were exploding things. I remember stifling back a yawn while the wife was whining for the nth time, and the only distraction was more things exploding all around.
And finally the last scene was something screaming out right since the beginning, could've certainly be made more interesting.
All in all, worth a watch, but puhleez if this is a classic, then the standards for classics have fallen abysmally! And people, a little more reading and watching of science fiction please, there's really a rich rich world out there!
