Apologies if they have been posted here before...
Maybe it's the design then. It looks fake to me or somehow too digital. Even if that's a real life model something just feels off with it.
The scene with the motorcycle going through the glass and Robo flying at ED looks pretty badass.

Nothing will ever top the stop motion stuff done in both Robocop and Robocop2, it's some truly top notch effects work and some of the best stop motion ever done imo.
