First one was better, but I still liked the second one. Only gripe was some of the boss battles took too long--especially the last one. They weren't hard in the sense that I beat most on the first try, they just took to long to get through.
The last one took me close to 2 hours as I wasn't dying but wasn't killing the boss either as it was healing so often. I eventually figured it out and beat it--been so long I don't remember what the deal was.
In any case, I don't need a lot of innovation in the third one. I'm more of a "if it ain't broke, don't fix it" guy with franchises. I mean a reach a limit eventually *cough* metroidvania *cough*, but as long as they don't run a series into the ground with too frequent sequels I'm fine just getting games that play more or less the same with just a new story and world.
