This Korean movie looked really promising and definitely has some great cinematography to offer. One thing is for sure, there must be a strange interest for war/army horror movies ... RPoint, Dog Soldiers, The Bunker and even remakes of those movies, well GP506 fits in between these movies fine. The movie is set on a guard post on the North/South Korean border where strange happenings occurred and a whole team of 21 soldiers got killed. The one surviving is killed when found blood drenched and wielding with an axe among the remains of the other soldiers. Since the army wants to cover up what happened one soldier is sent in to uncover what happened that night before 6o clock in the morning when an army troop arrives to cease the evidence. From here on the uncovering begins slowly (the movie is 2 hours long, so I expected it) and the new team of soldiers soon finds another surviving man who hesitates to tell his story. The movie is edited in an interesting way of flash backs telling the story fragments found in diaries and the movie soon turns out to be a mix of The Bunker and The crazies because whats behind it all is not the ghost movie you expect at the beginning. I don't want to ruin too much for you, because otherwise you'd spend 2 pretty slow hours to reach the final twist. The problem is that the movie is way to long and repetitive... the visuals are nice, the editing is interesting but it wears off soon. After all its a lot of drama elements in there and although there is some blood its rather on the sidelines for me. GP506 could have been a great movie but its way too long and fragmented for me and will sure not please the typical horror crowd with its ending. If you can't get enough of the movies mentioned before give it a try, but I think its not the same class even though the cinematography is superior to e.g. The Bunker.
