A particle has 0 spin and gives off two children particles with spins -1/2 and +1/2 (we don't know which is which yet, or they have to end up this way when we know one of them). If you measure one then you know the value of the other, so where is the mystery? They both had to have opposite values from the start. Whatever value I get for particle 1 then particle 2 must have the opposite value.

Whatever way I orient my detectors, and even if I get a higher than 50/50 value for the first, by orienting my detector the same way for particle 2 I should get the opposite value, so what am I missing?
