Combat-wise, Dark Souls is actually pretty rewarding, but it requires a lot of patience if you haven't been exposed to it already in some form. I spent a lot of time watching my roommates play before they finally got me to play, so I already knew and recognized a lot of things (and knew how to play against a lot of enemies.)
Really, the only "frustrating" part of DaS is that there are some things required to progress the plot (or sideplots) that you cannot figure out without a guide or multiple playthroughs. For those, though, there is absolutely no shame in asking for help if you get stuck.
