Al and I catch up on Series 3. Aliens, Explosions, Intrigue, not to mention Body Snatching. This is every kind of invasion story all wrapped up in one and it does an awesome job while it’s at it. Facing up to limitations both technical and practical, the producers of this show have forged a gem by making it’s weaknesses it’s strength. There are a good many Sci-Fi series that could learn a lot from their approach. Oh and for once we have a clean tag.
