I don't think this is just a T thing. There are some movies I just can't watch because the premise is ridiculous. Although I don't consider LOTR one of them. A lot of Horror movies for example. Dr Who is a bit ridiculous (it's still fun to watch though). Some medical dramas drive me absolutely nuts. House irritates me. That's not how medical diagnosis is done Ladies and Gents. (and I've been banned, by house mates, from watching anything fictitious and medical, unless it's MASH reruns). Anything involving crime solving, I think is included in the ban too.
Also anything that misapplies any scientific theory I'm familiar with, I'll pick holes and dissect for days.
Yes, it's a logic thing, but it's an intelligence thing as well. Some movies really aren't that enjoyable, because they require you to dumb down significantly. I tend to stay away from Box office hits for that reason.
