A word for 'excessively long'

I am trying to describe to a friend (who is trying to force "Broadchurch" on me) why it is I hate TV shows with such a passion.

One of my main reasons for being put off is that they drag on for an entire season, often comprising up to 10 hours of viewing time. Frankly, I'd rather watch Hugh Jackman's and Jake Gyllenhall's "Prisoners" which gives me the same thrill- ride in much less time.

One word that occurred to me was protracted, but I'm not entirely sure if that fits here, especially since it means lasting longer than expected, whereas a TV show lasts as long as it is meant to.

Solution 1:

I relate to your feelings for a film that does not interest you, seems too time-consuming and liked by a friend who cannot be persuaded otherwise. With that said, I personally think of something like "tedious", which may suggest some of the disdain you feel.

Other words: prolonged, laborious, time-consuming.

Solution 2:

Consider drawn-out or long-drawn-out

A long-drawn-out story.
