Bought this triple feature DVD set on Amazon, and I would say it was a good deal. Here's an overview:
This is another Sydney J. Furie directed Dolph flick. I think these two make a pretty good team. In this one Dolph is a supercop fighting corruption in a Rampart-style strike team. It's got a lot of fun 80's kind of action and has a classic buddy cop movie style. The opening sequence is classic cool too.
This one is a little disappointing. It's a Twelve Monkeys sort of scifi where Dolph is a soldier from the future who travels back in time to stop a plague from ravaging the Earth. Aside from co-starring Gary Daniels (who is egregiously underused here), this movie relies too much on crappy science fiction elements than it does on action. It takes place on an icebreaker in the arctic, which is kind of cool, but it's a little too much running around with dumb bad guys for my taste.
This one's not bad, but it's saving grace is the fact that the bad guy is Michael Pare'. This doesn't amount to much, but it does end in a nice fight and a fairly awesome death scene.
These are all three watchable, but I think Direct Action is the real winner. Either way, it's a good deal for the price. I think I bought it for under ten bucks.
