If you liked criminal UK, you'll probably be hugely disappointed by Criminal Spain. I'm unsure how accurately this show represents Spain's legal system but if it's accurate, the cops spend half their time trying to kick out the defendant's lawyer and the rest of the time asking about their vacations or backing up their nonsensical theories with their "gut"
Perhaps it's something lost in the awful translations but this show is definitely NOT up to par with its UK counterpart...
