I began following the series when it premiered in 1996. I was hooked on the first episode. What's immediately noticeable about this series is the realism, the splendid dialogue, the great performances of the actors and the overall plot. We've had quite our share of police series in Holland but none of them were as good as Unit 13. I think many fans of the series were struck with disbelieve when the VARA decided in 1998 to cancel the series after a successful third season. The only explanation I can imagine would be the huge costs of the series. It was not often that a series in Holland had tons of effects and amazing locations.
If you ever get the chance to get this series on DVD then I highly recommend to do so, you won't regret it!
