Neverending -- thanks for the heads up on Stir of Echos!

I saw Stir of Echos last night, so (_V_) you can add my spooky rating to the Stir total. Loved the subject matter of hypnotism, and sensitivity the spiritual world. Quality cinematography, shots, directing, acting. Found it hard not to judge it against other movies of it's general type, Dead Zone, Shining, Jacobs Ladder, (seeing dead goes back: Topper, Beetleguise, Frightners), 6th Sense, etc. Stir didn't really have any new take on this old plot line (wouldn't count hypno as new). Nice escape movie of the genre. I personally like 6th Sense much better.

All 3 films get more than decent scores, and are added to the opening post.

Some bipolar ratings
 

The Exorcist - 4.97

The Sentinel - 1.01

Burnt Offerings - NO DATA

Three great 70s flicks....

The Exorcist: 3 (Expect this one to score high, some amazing scenes and a quality movie, but 3 feels about right for me).

The Sentinel: 4 (Camp as hell, but so effectively creepy. Surreal and offbeat nature just add to the atmosphere.)

Burnt Offerings: 3 (Some really effective scenes, great cinematography, hugely atmospheric).

Two movies featuring the great Burgess Meredith too, his performance in The Sentinel is probably his best outside of Rocky... Quality actor.

The Exorcist - 5
The Sentinal - Can't recall if I've seen it.
Burnt Offerings - 3

The Exorcist - 2
The Sentinel - Haven't seen it
Burnt Offerings - 3

I know my rating for "The Exorcist" is probably going to cause a few raised eyebrows, but it just doesn't scare me.
