This is my opinion, the scores may have been higher or lower from when I saw it last.
Flight of the Phoenix
Audio = 7.5 or 8 Video = 5.5 or 6 (the original movie was better IMO)
Stealth
Audio = 7.5 Video = 6
The Island
Audio = 7.5 or 8 Video = 8.5+ (certainly one of the better movies lately)
Fantastic Four
Audio = 6.5 to 7 Video 7
The Brothers Grimm
Will let you know in a day or 2......
Also I can recommend (these are at least worth 1 watching or more); Kingdom of Heaven, Miami Vice Season 2 Disc 2 (disc 1 sucked), Sahara (was ok), Mr. & Mrs. Smith (was ok), The Five People You Meet in Heaven (is watchable), Herbie Fully Loaded (one of the better Love Bug movies), The Interpreter (Nicole Kidman can actually act), Fever Pitch (only if you like Drew Barrymore), Downfall (however this is in German with English subtitles), King of Queens Season 1 (all discs)(and I will be getting the other seasons as well)
Ones I would pass on(some were ok movies, but IMO they may not be worth being put in a collection, however they are in my collection); Four Brothers, Must Love Dogs, November (however, it was not that bad), Blizzard, The Perfect Man (and I actually like all other Hilary Duff movies), War of the Worlds (excellent sound but movie was mediocre), Christmas With the Kranks (tried watching this twice, because I could not sit through first watching), Crash (was not bad, but its not one I can recommend whole-heartedly), Hostage, White Noise, The Aviator (however, DiCaprio can act in this)
EDIT:: Just about to watch this (and I don't know why I bothered - but figured I'll give it a try)
Dukes of Hazzard
