请分析下这句语法

as impressed as...作句子的状语，状语的主语依旧是主句主语television executives, 但这里有个问题，句子逻辑上，状语部分应该用否定式才合理： But not as impressed as consumers say they are by the aesthetic and style of print ads，televison executives(as you might expect) dismiss the findings. 这样的话句子意思是，但是电视台主管们并没有像消费者自称的那样被打印广告的风格和美学打动， 主管们并不承认这些调查结果。或者如果状语部分保留肯定语义，那需要用Although: Although as impressed as consumers say they are by the aesthetic and style of print ads，televison executives(as you might expect) dismiss the findings. 虽然电视台主管们和消费者一样被打印广告的风格和美学打动，但是主管们并不承认这些调查结果。

这是主系表结构，then 是插入语，
〔主语〕that
〔系动词〕is
〔表语〕Clare college
