led to believe by the other comments here. OK, it was low-budget and the final sequence could have been extended and it is unclear why the imploder's lights are the opposite of those in the first film, but it does work as a sequel, picking up where the first movie ended and building to a resolution.
If you get the DVD with both movies on it, give this one a watch and see for yourself.
