I almost played through the whole thing in one sitting. I got my ass handed to me several times in a rooftop scene, finally figured it out, and I got to the streets again. I thought that was the perfect place to break free. It is very compelling. The graphics tech is not very impressive, but how it's used alongside the dialog and the rest of the audio is really effective. I've had several nightmarishly chilling moments, hairs going up on end, all that. The characters seem very alive, despite their static eyes and faces. Motion capture, voice acting and scripting go a long way there. And of course, the premise is great fun. It's gotten so that the slithering-eel exploration and attack is what I use nearly all the time. The darklings seem very weak by comparison, though I do like the 4th one a great deal. Darklings were more useful when my powers were weaker.
I've found other things that play on TVs--several cartoons, music videos and The Man with the Golden Arm, an old Frank Sinatra movie. I did not watch much at all of that one. Time has not been as kind to it as it was to Gregory Peck's defining vehicle.
