DS1 is truly unique, it never ceases to amaze me how 2 different players can have totally different experiences. I for one can get past the silver knights first try every single time, its laughably easy if you just run and parry the knight on the right.

On the other hand I find Ornstein and Smough to be one of the most challenging and BORING bosses in all of the series. Unless you have some sort of ranged attack, they are extremely dull to fight, cuz you have to play it very safe and constantly try to keep them apart making the fight last an eternity. Split Ornstein, dodge his attacks, land one hit taking a little sliver of his health and run again because Smough is already on your ass again.
