Time Out says
Soon after this fair-to-middling adaptation of his sci-fi novel, Michael Crichton took to directing his own scripts. No connection necessarily, but Wise does rather plod through the plot, so that when his scientists finally make the connection between the micro-thing from outer space and a secret bacteriologial warfare project, it seems high time indeed. After a spendidly traditional opening sequence, the message about the dangers of scientific research begins to loom ponderously large, with banks of super-computers dedicated to science fact but the dialogue ('Good God, it's growing!') still mired in fiction.
