It is fine that you don't like Baldur's Gate, but you really seem to be missing the fact that it was reviewed well, sold well, and has a huge fan base. It was a very good game for many people. Quite a few people who consider it a classic. It appears regularly on top gaming lists.
Personally I prefer the BG1 experience. I recognize that is not the majority opinion, but I'm surprised you aren't recognizing how important BG1 was. If it wasn't such a successful game, we probably never would have had BG2, PS:T, IWD, or NWN. It was the rebirth of the Forgotten Realms and D&D PC games, and BG1 was catalyst.
I replayed BG1 a few months ago and enjoyed it just as much as my recent Fallout play through. I know quite a few folks who do this.
