Got this through the post yesterday morning, just now completed it. I enjoyed every moment tbh, i was worried they wouldn't live up to the original but for me they have. I'd argue it was a better game as there was no backtracking at all (technically, i guess the return to you know where could be considered backtracking

) and there was more variety. The direction in some of the cutscenes/QTE sections was just brilliant, i especially liked the way the ending was directed.
My one complaint was the return of everyones favourite enemy, i didn't like him in the first game and i still didn't like him in the second.
The ending brought a grin to my face too.
[EDIT] Oh, i didn't adjust well to the fact that you ideally need to buy ammo every now and then in this (in DS1 you never needed to buy ammo, even on the highest difficulty) and that you should buy lots of nodes. At one point i had over 200k, that's when i realized i should start buying nodes, then the game got MUCH easier as i went from very weak weapons to uber weapons in one go. Even at the final save point i had over 100k, so just bought nodes and spammed them.
Spear gun was my fav weapon

. Came in handy against everyone's fav enemy, one shot, electrocute, explode, nothing left.
