I watched all 3 and at the time loved them. Looking back yes they're all bad, but they have their charm. Syber-Squad has the best music, and you can't go wrong with Tim Curry. It tried too much to be like Saved by the Bell at times. It was my favorite of the 3 due to having transforming robots unlike the other two, and I really liked Servo.
VR Troopers could have been much better. Beetleborgs suffered from the child actors and cheesiest villains out of all the programs. The acting was pretty bad. Some characters got it right though.
