I have heard a lot of people (friend, family) try this game back when it was released.
A lot of them had the same complaints and they aren't really into game reviews and such (talking to much, having to walk back and forth) and most of them didn' like the game other than the detail and visuals. Upon seeing it they were really interested but after they tried it for 30 min. they wanted to play something else. I can get that the game isn't for a lot of people and that is fine. I personally enjoyed the work, fighting story elements.
I do think there is a lot of room for improvement in the mission structure and design, and SH2 did fix some of that. I hope it will be improved upon for 3.
