Can't even finish them...

In my youth I would never, ever leave a movie unfinished. My philosophy was that any film - no matter how terrible, could be redeemed in the last frame or two.
Anyway, as an adult, and more specifically - a father, I have fallen into the nasty habit of not finishing movies. My wife is frequently a co-conspirator in this dilemma.
It goes like this:
She wants to watch a movie, but not a "boy-movie" (which should read as all genres other than rom-coms and dramas with lead female characters). Basic requirements:

• Something funny. 
• Can't..absolutely can't have subtitles.
• Can't have robots. 
• Or be in space. 
• Scary? No. Don't even ask.
• Can't be part of a trilogy.

I make the pick, and fairly soon - she's out cold.
What do you do? Finish the movie and then have to watch the second half again? Or stop and play Xbox or watch Sportscenter? I usually just call it.
Now, don't get me wrong - it's not all her. Lately, I fall asleep. My son wakes up. Something happens and the whole train is derailed. Here are some one or both of us are working on for various reasons...

I keep falling asleep.

100% solo mission.

She went out quickly.

We both fell asleep.
