We have to confront a hard truth that few people seem to want to face about the Souls games, but here it is: the combat is nothing remarkable.
In terms of actual complexity there's not much going on. There's not much depth, and that wouldn't be a problem, except the series has increasingly leaned on its action elements more and more as time has gone by.
If you're a staunch defender of the series this is where you might be tempted to rattle off all the attack animations your favorite weapons has... It's true that there are differences in range and damage, but the effect on the enemy is usually identical. They lose some health, possibly suffer some hitstun which either lasts long enough to get another attack in or it doesn't, in which case you go back on the defensive until your next opening. Positioning is important, but that's about the extent of it.
In terms of defensive options the series is a lot better, with the ability to block, parry, or dodge most regular attacks...Unfortunately, against bosses, parrying is often completely impossible and blocking is often ill-advised, which leaves you with rolling as your one and only defensive action. So prepare to roll again and again, and again and again and again. When you're not rolling you'll generally be getting 1-2 hits in with whatever weapon you choose, hits that usually provoke no response from the boss whatsoever making every weapon basically the same thing apart from whatever damage types and numbers it has.
You go in, you learn the moveset. Maybe you die a few times along the way, until you know the boss's moves like the back of your hand. Then you dodge past them, punish at the right times, and win the battle. It's perfectly serviceable gameplay but doing it 20x in one game is just excessive.
I'm not saying you should be able to juggle Hollows or anything, but if the game is going to be so relentlessly focused on action then I have fewer reasons not to just play a better action game.
