I've always felt the opposite, that Resurrection is much easier to get into if you're unfamiliar with the original PS1 game, because my experience with the game mainly consisted of my annoyance at the childish cartoon take on the story and characters of the original (which was made much worse by the Jar Jar Binks character that you're stuck with for the entire game) and being forced to constantly use the awful, broken combat system. I'm not going to pretend that MediEvil 1 and 2's combat was anything to write home about, but they were at least adequate for the PS1 and, as GVZ said, the weapons actually felt like they were hitting something. As for the two handed weapons, I've been playing through Bloodborne and it handles one and two handed weapons in pretty much the best way it could. Every weapon has it's own specific strength and all of them can be great depending on how you build your character around them. MediEvil 1 and 2 were somewhat similar because weapons like the warhammer, battle axe, and flaming longbow had their own unique traits that kept them useful even after you acquired the magic sword. Resurrection isn't like that, though. The terrible sluggishness and hit detection makes the hammer and axe completely useless, setting enemies on fire has almost no practical effect, the chicken drumsticks are nerfed to only affecting one enemy at a time, and the list goes on. The long sword, magic sword, and Woden's Brand are the only weapons that are actually good because they're able to hit the enemies most of the time.
At least if you're unfamiliar with the original, or you don't mind the new atmosphere and aesthetics, you can appreciate the game for it's graphics, voice work, soundtrack, and comedy.
