furthermore with realistic zombies a tendency to climb would be possible, however jumping wouldn't work so well. also they wouldn't burn in sunlight, and even more realistic is the rigor mortis factor, in which the body would gradually become stiffer at a set rate and then begin to relax back to normal at the exact same rate... so really modifying zombies to suit every individuals expectations could become a much larger undertaking than one would think. there is also the decay factor... how long has the zombie been dead? anyways... i love a good zombie talk as much as the next guy but modifying zombies would be a huge task on its own....
