I actually just picked this up for a rental a few days ago (still cant get a copy of darksiders :/)
when i played the demo i was actually a little surprised, i knew the guy who created this also created DMC but the character bayonetta herself didnt really catch on to me like dante did. Anyways retail copy wise im about 5 hours in or so on normal and i have to say im really enjoying it. The fighting and controls feel very dmcish which is a good thing, but it also has its own little twist to it. Equipping to both arms and legs is awesome i might add, the controls are good enough that you can string combos together somewhat smoothly, the slow down time makes evasion fun as well, if you perfectly dodge an attack right before impact you go into "witch time" which slows down everything but yourself, makes it useful on fighting enemies.
The one thing that bugs me though is about around hour 3 or so the monsters just start getting thrown at you so i find myself dying alot, its not really the mass amount of the small enemies its when they throw two semi bosses at you at once.
oh and after playing the dantes inferno game my appeal to it died a little more, dantes inferno is the ultimate heck and slash for me =P
