It’s another BDO (Big Dumb Object) story! Not the best Crichton. An large sphere is found underwater. Divers are sent down to investigate. Strange things happen. Gee, wasn’t this plot copied for Clarke and Lee’s “Cradle“? Anyway, fun for the SciFi and Crichton buff, and probably ok for everyone else. On a side note, the movie is actually pretty decent. Scary in that Alien way.
