There's a bit of a curve in there that kind of works itself out over time, for me.
When I first smoke a blend, I'm more attentive to get a feel for it. Not sure if I'd call it critical so much as being mindful.
Sometimes, I load a blend, hoping it will recede into the background and become mindless enjoyment as I do other things. Other times, I hope for an experience upon which I can focus.
Often, the pipe and tobacco do as they wish and I adapt, being more or less mindful as dictated.
Rarely, the smoke will become distracting or not enjoyable and I will sit it down, but that's definitely the exception.
I think I subconsciously choose more or less intricate blends to match my mood.
