The review by John Griffin which appeared in this morning's Montreal Gazette wasn't very nice :-)
Here is part of it...
"This movie gives stupidity a bad name. It's a summer popcorn feature that can't find its own mouth, a story so entirely lacking in credibility that you can't just sit back and watch it - this kind of blanket ineptitude forces an audience to actively find entertainment in its mistakes"
Guess this means the cult will order all its members to see the movie ten times so Travolta won't lose too much money? :-)
