Comic Review: Batman '66 #23

On the actual Batman TV series, which this comic is based off of, one of the most memorable gimmicks of the show was that every episode was a two-parter. In this issue, and a few others in the series, they have done exactly the opposite, taking two separate but sometimes related stories, and telling them both in a single issue. In this case, we have "Monsters A-Go-Go", with stories focused on Solomon Grundy and Clayface.
