watch ghost of the abyss on the big screen simply take my breath away . the photography be simply majestic and and will leave you in awe . if you be a hard core titanic buff and you will recognize a little of the footage from another documentary that cameron do at the same time a ghost . the 3 d effect be pretty interesting and but probably a bit overrated . this would have still be a fantastic documentary on the big screen even without the 3 d effect . it do make it very interesting though . they go into part of the ship never see before so it be very good . i leave wish it would have last about 2 hour longer . even 90 year later the ship still have the power to take your breath away . i would rate this a 10 for people that truly love the titanic and but maybe only a 7 for those do not . i leave this movie feeling that jam cameron really have a love for the ship and really believe in what he be do and and not that he just do it to make a buck like some have suggest . a must see for any fan of the great ship .
