if you missed seeing it in the IMAX you really lost out.

The film was shot specifically for the IMAX using IMAX cameras for many scenes. It did not feature 3D -great in my opinion- because Christopher Nolan does not prefer 3D.

Seeing it in its true IMAX format was simply amazing.

There are a lot of movies that are displayed in IMAX theaters but this particular movie was specifically shot for the IMAX format with IMAX film.

Almost all other movies (ie Avengers) that are displayed in the I-MAX theaters are not actually shot with IMAX cameras, they are simply filmed with standard (lower) resolution cameras then cropped & converted to 3D.

You'd have to have seen it to believe it. The difference is huge. I saw TRON II in an IMAX and it sucked big time. But I have seen 3 Christopher Nolan films in IMAX and all were amazing because he uses actual IMAX cameras to film.

Also note there are a limited number of "TRUE" original sized (120+ ft) IMAX cinemas in the United States. Most of what people now recognize as IMAX are simply new/old smaller theaters with new digital cameras. The original 4:3 ratio giant theaters are located mainly near major metropolitan areas. Example: Metradome in San Francisco, Spectrum in Irvine.
