I cannot comment on the differences in video quality between this and the non-superbit version, as I have not seen the non-SB cut, but this cut looks excellent.
The DTS track, which is only available on the SB disc, is phenominal! In switching back and forth with DD, the sound is more open, dynamic and fuller to me. Great use of the surrounds also. some scenes had me thinking the sound was coming from outside!
Besides, it is just a fun movie. Highly recommended!
