Comic Review - 2000AD Action Special

I thought long and hard about actually getting this, considering I've seen it described as an atrocity. But a cheap copy came up, and I thought "How bad can it be?". One question that always springs to mind when you read these things is why exactly writers bother bringing back characters if they're going to totally change them... In this way, this thing's a decade ahead of its' time, foreshadowing the damage Marvel and others would do to their characters around the turn of the 21st Century.
