I resent its cynically shallow pessimism disguised as apple pie sentimentalism, its artistic laziness & its technical sloppiness. I resent its condescending attitude towards its audience. By virtue of its sheer popularity on IMDb it's a testament to the colossal, continuing dumbing down of movie audiences.

Where to start on specifics? The premise of a world-wide drought (a major blooper mentioned on this site) with tall green stalks of healthy looking corn. Okra grown as a major food crop (or was that supposed to be a joke)? Cut & paste interviews from a Ken Burns documentary abut the real dust bowl. The tiresome cheapie "homages" to Kubrick's 2001. The pedantic Astrophysics for Dummies lectures.The soap opera characters. The one dimensional acting. The utter predictability of every single plot twist. I'd get more specific, but then I'd be blacklisted for including spoilers.

You want to see imaginative mind-blowing science-fiction/fantasy film making? Let me make 2 suggestions: Stalker and Solaris. Both Russian films directed by Andrei Tarkovsky. Far lower budgets than Hollywood blockbusters but works of pure genius. Avoid the American version of Solaris. It's a travesty, though not quite as awful as Interstellar.

In summary the sheer numbing dullness & stupidity of Interstellar (& its concomitant popularity) managed to knock me into the worst state of depression I've experienced from a movie in years.
