It's a great game IMO. Gets a bad rap for whatever reason. I thought it was epic at times. Crazy good fun.
On PS3 the load times are absolutely atrocious (may be better on X360 with HDD install?). Honestly I thought it the combat was good, the general idea was ok, but the execution was pretty piss poor. Run through a zone, fall into poorly marked 'radiation' 4-5 times, get to the combat, hit the zone-line - wait 5 minutes for load - wash/rinse/repeat.
