The Church of Scientology is evil and its members should all burn in hell...and that's just for roping Travolta into making "Battlefield Earth".
Although I formly believe the Church of Scientology is a misdirected cult, the film 'Battlefield Earth' did amazingly reflect some serious study into the the nature of angels. I suspect the aliens depicted much closer represent many a breed of fallen angel and a fallen perspective of holy angels than many other depictions.
Just remember when watching the film that it is intended to deceive and is presented as though it were science fiction and imaginative rather than based on any serious study of that domain.
