This quirky indie sci-fi movie is superb on several levels
Before I forget, I must state the following:
1) This movie foretold the advent of the ipads. The characters are liberally using the hand-held ipads at the end of the movie. At first I thought this was derivative of the Star Trek ipads from, 'The Next Generation' tv series. But the characters amazingly foresaw the widespread application and use of ipads some 12 years ago.
2) I now believe the characters were still in the game at the very end. Notice how everyone reacts to the shooting of game designer, Yvgeny Nourish and his personal assistant, the skinny redhead, Merle? Everyone just sat there and stared blankly at the shootings. This was similar to the Chinese restaurant scene when Ted Pikul shot the creepy Chinese waiter in the face and all the diners and cooks sat there staring. In real life everyone would have either cringed on the floor for cover or ran out of the building screaming and yelling.
3) It is difficult for science fiction movies to garner critical review. There has to be some very strong metaphysical, existential, psychological, dramatic or underlying theme. It is very rare for a science fiction movie which has none of these to achieve critical four-star review. The only one I can think of is, STAR WARS THE EMPIRE STRIKES BACK. Other than that, the few science fiction movies that achieved critical fame include, Blade Runner, the Matrix, and Soylent Green, to name a few. I believe director David Cronenberg was trying to achieve this with eXistenZ and in my opinion he succeeded. Cronenberg has always been noted for his unusual, particular style of atmospheric science fiction movies, for example, the cult classic, Scanners.
If you accept eXistenZ for what it is, an atmospheric, almost neo-gothic science fiction film on a metaphysical level then you'll understand and appreciate the movie.
