Well, that wasn't what I was expecting. Rather than a funny look at stone age life a la the cartoon I remember as a child, I was faced with an interesting commentary on social issues.
PTSD in soldiers
Treatment of immigrant labour
(Gay) Marriage - Kudos for Fred standing up for the 'non-breeders' right to marry.
Government manipulating troops into attacking innocent tribes just to get their land.
It was darker than I thought it would be. I was grinning as I started, because Fred had to show a group of Neanderthals a night on the town and one of them had such joy at being in Bedrock. Everything was new and exciting to him and you could see the joy on his face as he skipped over to buy a balloon from a stand on the street and won himself a hat from a grabber machine. And then they killed him off on a whim from Fred's boss and the whole tone of the comic changed for me.
The artwork was bright and bold but the story was far from this and the humour was dark.
