this was the worst episode featuring the Riddler but I think he is such a great villain that his worst episode is pretty good. The hole plot was really well written and all the riddles were really good, like the doors part the chess part and the coins part. It was pretty useless that the Riddler took Batman to that car place because he wasn't there, only with a van to kill him but that's not what the Riddler always wants, he wants to challenge Batman. Overall it was a nice epiosde, but I personally prefer the other Riddler episodes like "If you are so smart why aren't you rich" and "Riddler's Reform"
