The last new movie I saw in theaters was Shutter Island. A decent movie, but easily Scorsese's worst.
The last movie in general I saw in theaters was Jurassic Park in IMAX this past April for the 20th Anniversary. Never gets old.
Still, fuck the theater in general. No movie in the past 3 years has gotten me so excited that I couldn't wait another 4 months to get the Blu-Ray from Netflix.
