Hey I love Star Wars. And R2-D2 is a decent character in the original series, but does he really need to be in Episode VII? It's bad enough that he and C3PO were in the prequels to tie the whole mess together. "Oh, Anakin built C3PO and R2-D2 saved the whole gang when they were on Amidala's ship! How amazing!" Then George Lucas retroactively gave him abilities like leg rockets in the Prequels that he didn't have in the original trilogy. Where did the leg rockets go, George? Did he forget he had them? R2-D2 has become Doc McGuffins in the series! Leave him out, J.J.!
