I was also really mad when I realized how much Power Rangers (which I hate with a passion) is such a ripoff of Voltron.
Next week someone is going to tell you that Santa Claus does not exist and is actually a rip off too. Don't be mad at him/her ok?
I'm sorry, just ignore my rantings. I will leave you all for a good debate on this topic. I'm desperately in need of some alcoholic relaxation.
