Regarding 'The host wasn't actually that bad':
The Caldwell season of Tic Tac Dough, especially the second half of it (thanks GameTV in Canada!). Having seen samples of his work on Top Card, which was generally very good, I'd always had a curiosity as to why folks seemed so particularly contemptuous towards Jim Caldwell's season of TTD and towards him in particular. GSN dropped it right as I got the channel, so I only had a handful of episodes as a sample - and it wasn't a show most folks had taped so there wasn't really a chance to trade for it (or to get a run of several consecutive shows for context).
Thanks to the season's more recent Canadian reruns, got to eventually see basically his entire season. While Jim himself starts off rough and with a definite level of robotic-ness and clearly having been over-coached, by midseason he's clearly gotten the flow of things, has figured out ways to tweak things the show wants him to say to sound slightly less phony (although even end-career Bill Cullen on TJW struggled with this.). Almost all of the B&E shows suffered with issues with the show clearly wanting their emcees to act a certain way, phrase things certain ways, react in a certain manner, don't forget to go for the pun...Jim Peck probably made the "B&E Style" look the most organic (while not having the pacing issues Bill did), but late-stage Caldwell was getting there.
Most of that season of that show's real problems weren't Jim. The re-done set was hideous, even for 1985-86. Yet they kept the distinctly late 70s cheeseball theme (it's not bad, but it's very of-it's-time. And while the red boxes weren't a terrible mechanic, their over-reliance on host spieling meant that a rookie emcee already being coached to overexplain, point out the obvious, and in generally be a cliche* meant that the show itself did Jim no favors.
By year's end, Jim's found his groove and is orders of magnitude better than the initial perception and judgement. It's honestly a shame GSN dropped the show (their last aired was right around 115 or so of 175) RIGHT around the time Jim turned the corner. His last episodes had me genuinely wishing he got a second season.
*In fairness, I also happen to find Wink incredibly overrated (there's a reason his best show, Debt, contains a measure of self-parody). Which makes me more receptive to the "new guy" over "the guy who was here the last seven years". And there's a reason the "Mr. Game Show" toy of the late 80s and many pop culture depictions of game show hosts tend to be most evocative of Wink.
Also, add me to the list who thinks that Pat Finn was generally good and occasionally great - and that he was just done absolutely no favors by Shop Til You Drop [my #1 guilty pleasure] and TJW '90 [which got dramatically better with format #2].
