I recently watched "Interstellar" for a second time, initially having forgotten that I'd already seen it. My wife and did a lot of "gee this looks familiar". She remembered more of it than I did (odd, because my memories of movies is usually much better) and as we talked about it more and got to recalling the ending I said, "This is *that* movie? That was terrible!"

I think I was so annoyed at the ending I'd blanked out having seen the movie at all.

Second time through, I feel the same way about the ending. Terrible. "Deus ex machina". Ticked me off as much as the ending of "Arrival" did. And it's really a shame, because the rest of the movie was pretty well done. Nice world building, stunning visuals (if at times a bit too 2001- ish), pretty good acting, plot, pacing. I'd love to want to watch this again for all that. But I will never do that, I would not want to experience the ending again.
