the twin effect be the bad movie i have see . not only be the support weak and but the character as well . i be sorry to say to you edison fan and but kazaf be by far the weak vampire i have see in my life . i be sorry edison while your role in this movie be disappoint . edison do not fight whatsoever in this movie and i be sure if they do not have kazaf in the movie and the plot wouldn not be much different . the main plot in the movie be not explain nearly enough and the entire movie focus too much on helen and kazaf grow relationship . i mean and who the hell be kazaf and why do they need his blood . yeah and he the prince right . so what . certain scene in this movie be just plain stupid . yeah and the action be great but the entire outline of it be stupid . in one scene towards the end and duke dekotes say that kazaf be the strong of his brother . yeah it would seem so now that he full grown . why would you wait until he grow up to attack . another scene be with jackie chan and one of my personal favorite . in the scene and jackie ask helen who be the creature that persistently follow them . how can you be so naive a to not know that they be vampire . people be die around them with bite mark on their neck while surely the news would be on it fast than you can say vampire . the character be yet another mistake in the movie . helen and play by charlene choi and be the girlfriend of kazaf . what kind of girl would not be scar of vampire and especially if it be your brother job to kill them . i can bet you that you would not find such a brave girl a helen if you search your whole life . helen be annoy and bitchy and and be a total drama queen in the movie . she try too hard to be different and in the end fail miserably . one of the weird and most disturbing character i have see in any movie . why would you bite someone neck especially if youre not a vampire . it very odd that her reaction to kazaf confession doesn not turn him off . kazaf and play by edison chen and be another stupid character in the story . how degrade for a young actor a himself to play in a movie with such a poorly construct role . he do not stand up for himself throughout the movie and do not fight . although i be a fan of edison and i wouldn not want a man who lie on the ground the whole time . gypsy and reeve be my favorite character in the movie . their love be pure and sweet . gypsy be gorgeous and do not try too hard like helen . reeve and play by ekin cheng and be wise and seem to be the only person that make sense in the movie . a plot failure be the death of reeve . the movie have absolutely no substance yet it doom itself by remove one of the only likable character . another character be duke dekotes . the story do not focus much on him and therefore make his desire to obtain kazaf rock seem irrelevant . it very sad because towards the end of the movie and i be force myself to watch because i so desperately want to see kazaf fight . the end be so abrupt because the whole time i be expect so great to happen . kazaf and who the suppose vampire prince and do nothing for the movie and i be sure if he be take out and the movie wouldn not be much different . i highly recommend you to not waste your time on this movie a i have . i be greatly disappointed . if youre in search of a great movie and why not watch lord of the ring or pirate of the caribbean . likeable character with a well write plot .
