Anaglyph 3D was all the rage in the 1950s and had a brief resurgence in the '80s with some memorable titles like Friday the 13th 3D and Amityville 3-D, which always suggested a better time than it was actually able to deliver.
In a complete departure from the first two films, it focuses on Brody's kids, who now work at a SeaWorld marine park, where a great white makes its way in through the gates and terrorizes the parkgoers. There is approximately one scene in this movie that remains completely memorable (and makes cheesy use of its 3D novelty), but the rest is pretty hokey and can safely be skipped when going through a rewatch of the series.
