Sure, Cullen was slower, no doubt. But by slow in general, I mean the entire flow. I get the gimmick, and hell, Joker was my childhood favorite show. But the spin, pause to decide, frequent exposition by the host, question, etc. wasn’t exactly a breakneck pace. They got a few games in on average because the winning threshold wasn’t all that high, and some games just ended ultra quickly with big spins or the triple Joker instant win. TTD and Bullseye games took longer with their gimmicks but the pace of questioning wasn’t all that much faster (especially the center box on TTD 😉).
The formula with the slightly altered packaging worked for them, and more power to them. They had nice, successful runs. I look more to a show like Jeopardy as being fast paced with typically 60 questions a show excluding final.
Turing Joker into Hollywood Squares with a slot machine certainly made it even slower, but more like a regular steady walk a leisurely stroll. It was certainly interesting to see it.
