This is the kind of sequel that can be rather enjoyable as long as you don't hold it up to the standard of the original. It does bear the signs of a movie that was conceived primarily to capitalize on the popularity of its predecessor, and as a result it is hardly as carefully constructed. But as light entertainment, it works well enough.
The first part of the movie connects things up pretty efficiently with the original story, and it's kind of fun to go back to André's wrecked lab, which looks just as it should. Brett Halsey plays André's son Philippe, who is determined to follow in his father's footsteps. While the setup could have led in a number of different directions, the story that actually follows puts an emphasis on action, and it uses the special visual effects rather more freely than in the original "Fly".
From a scientific viewpoint, the whole premise of both movies is far-fetched at best, but in the original, you rarely thought about it because the story was so tightly constructed. In the sequel, the implausibility of the whole thing is harder to ignore. It doesn't detract that much from the entertainment value, but it is a noticeable difference from the first movie.
Except for Vincent Price, the cast is new, but solid. While the production might have a couple of rough edges this time, most of it still looks good enough. Overall, with the right expectations this is a generally entertaining light feature.
