i haven not read the book of this and base on this adaptation and will not bother . i hat every character in this show miranda be slutty and selfish and mumble miserably through the appalling dialogue and her sister be a total wimp and and this be the bad depiction of manic depression i have ever see . i have a degree in psychology and and this be not accurate . in fact and until it be mention and i do not realise troy be suppose to be bipolar i think he be a normal and slightly grumpy teenager . the only save grace in this stupid show be david tennant and whose brilliantly psychotic performance be the only thing that get me to watch the second half . clearly the writer and producer of this show have not do any research troy mental problem be not remotely accurate and nor be the forensics involve in the twist end ( and if you do not spot that a mile off and you be a big ole dummy . ) utter garbage .
