Although I gravitate toward Playmobil's historical themes, I don't hate any of their themes. I don't really love the Ghost Pirates or the new Secret Agents, but I see their (probably temporary) place in Playmobil's lineup.
I agree with Wesley that I don't like the execution of certain sets like the purple barbarians or the current pirate ship, however I disagree with him about the inclusion of firearms in the police theme. These are realistic tools that the police use everyday, just like a fireman's axe or a doctor's stethoscope.
