I was actually a fan of this movie.  After reading an interview with M. Night Shyamalan stating that this was intended to be the first part of a trilogy, I grew to appreciate it more as a setup movie.  In a way, it was the Batman Begins of an unknown superhero.

QUALITY:
Great.  Surprisingly better quality than Warner Bros. release of Shyamalan’s Lady in the Water which was a much newer movie.

BONUS FEATURES:
An early Shyamalan film, featurettes, deleted scenes

Featuring all of the bonus features from the two-disc “Vista Series” released a few years back, there is really no reason at all to NOT replace your standard DVD with the Blu-Ray version of this underrated movie.  The only issue is that the bonus features are only show in 480i but, they were originally produced on non-standard film cameras so high definition would be a nearly impossible task.
