Why add to brilliance?

Rating: Null/10 (30 September 2000)

I just saw the reissued "Version You've Never Seen". I was
mortified!
Why did they feel the need to add those 11 minutes? There
was nothing in it that clarified the plot or did anything but
make it 11 minutes longer. Most of it was dialogue that is
represented elsewhere with the exception of the spider
walk. And the spider walk doesn't make any sense...why
does she have blood dripping from her mouth? Did she bite her tongue in her sleep or something?
Also, why did they add those effects? When Chris walks in
the night that Burke is killed, you can see one of the
subliminal faces flash in the hood of the stove and an
image of the statue in Iraq in the corner of Regan's bedroom. That wasn't in the original release as far as I
know...why add it? I also noticed a digital effect before
Regan attacks the hypnotist where her face morphs into
one of the subliminal faces for a split second. Ew.
And what's with the extra underscoring and sound effects?
Moments that were completely silent in the original release
had "Shining"-esque chords under them. Also, I noticed a
lot more background noise in the crowd scenes...most notably when Kinderman is talking to Karras, there are
some obnoxious college students talking rather loudly and
obscuring the dialogue.
All in all, I'm glad I got to see this movie in the theatre.
However, why all the additions that made it less effective?
