Currently on a Columbo binge. I've always liked Columbo, but doing a binge makes me more critical, and as we go along the series, I find that the evidence gets more and more flimsy. The murder always confesses, but I feel most of these won't hold up in court. They'll come to their senses, hire a good lawyer, and either there will be just circumstantial evidence, or any evidence would have been obtained without a warrant or as a poisoned fruits. This gives me the idea for an anti-series starring a lawyer who is hired by the murder Columbo has caught, and who tears the case apart in court. He always has Columbo on cross and everytime says "Just one more thing." during the cross.
That could be a fun series.
