I am a big fan of "Police Story" and love my Season One DVDs. Sadly, however, the rest of the shows are not available on disc and the only way I am aware of that you can see them is to find them on YouTube...and SOME of the episodes are posted there.
Compared to the several dozen episodes I've already seen, "Robbery: 48 Hours" is a lot less enjoyable. It even comes off as choppy and less fun. Why is this? Well, it's fundamentally different from other episodes because instead of focusing on one cop or a team of two cops, this one is about a unit which is working to stop armed robberies--and there are tons of men in this unit. Because of that, the personal touch is missing. Now I am NOT saying it's bad...but it is noticeably less enjoyable and well made because of the style. Still worth seeing....but a bit of a disappointment.
