Female Leads and the Providers who remind us of them

Let me start this out by saying I enjoy watching TV during my down time. For those of you who also enjoy the ol boob tube do you notice how many shows get canceled right as they are getting good? In the past I hardly ever caught new shows before they made it to season two or more so they had proven lasting power. I notice now a days that shows come and go as the wind blows and some of they I see from season one and am disappointed when they go (guess I'm the only one otherwise they wouldn't go huh). This brings me to the hobby point of this. If I find the lead lady or supporting lady attractive it is nice to find a provider lady who reminds me of her or looks like her. Do any of you also notice similarities between hobby providers and some of the ladies you enjoy on the big screen. Feel free to share examples.
