Into the Nexus was actually a really good R&C game, though it was about 75% shorter than normal (I think it was originally planned to be episodic).
Full Frontal (on PS3--the Vita port was an atrocity) was a decent PSN title, but it didn't need to lean on the R&C universe--it would be well suited for a PS4 title, especially with the much better online MP suite that the new console offers. Same goes for All-4-one.
In any event, the main-line R&C games on PS2 and PS3 are some of my all-time favorite games (A Crack In Time was a nearly perfect gaming experience in every way), and, thus, I am pretty excited to see the movie, too.
