Honestly I don't know how critics do it. Physical art critics, maybe--time means nothing. And book critics can go back and forth.
But when it comes to movies, television, theater, most any temporal art (though not always music), I am there to dissolve into the experience. My disbelief isn't suspended, it's part of the ticket price (unless it's Jupiter Ascending because what was that anyway): I hand it over walking in to the joint. Unless the show is truly bad I can never disconnect enough to interrupt the immersion. I want it to be good, always.
It makes me a terrible postmodernist but sometimes I wonder if I should put more thought into the art and structure of movies, of television, if I wouldn't enjoy Game of Thrones more if I could spot themes and tropes as I watched, rather than reading the obvious a mere hour later on Vox or AV Club or even Reddit.
But as a kid, watching Harryhausen movies and whatnot, I didn't care about the technical details, the arc of the plot. I didn't think about the salaries involved getting all those villains together for the (tv show) Batman movie. I didn't think about some poor dude sweating his ass off in that Sigmund the Sea Monster costume. And as an adult I have to wonder, can't I watch a Gaspar Noe movie without wondering how the sausage is made?
