One is that I loved the cast. I thought everyone was well-picked for the parts they play. A lot of my personal favorite young actors and cult favorites are amongst them like Henry Thomas, Madchen Amick, Frank Whaley, Brion James, Shawnee Smith, and Victoria Jackson.
The film is also major sci-fi eye candy. The direction and the special f/x remind me a lot of the film STRANGE DAYS, which is another film that serves as sci-fi eye candy.
And it's also just one of those classic plots that was put together so well in a revised sci-fi version that others have tried to do, specifically PARANOIA 1.0, but have failed miserably.
I enjoyed BOMBSHELL, and if you liked STRANGE DAYS, you will probably like this film.
