I'm making English subtitles for a French film and I'm having trouble with this sentence:
When you watch a Hitchcock film, you work all the time.
When you're watching a Hitchcock film, you're working all the time.
I just can't decide between the two. Oh and while I'm at it, do you even understand the sentence? It's supposed to mean that you're an active viewer, your mind is at work. But does it make sense, 'you (are) work(ing)' ?
