If you take the Gamespot review as an example, its tone was very lukewarm. The main criticisms were of the graphics, combat and bugs.
Troika seem to have got most of the bugs, but when I played the first time as a human character, there was a vital point in the game when my intelligence always sank to 1, and there was no patch available at that time. It was very annoying, but I replayed as an elf and avoided it.
I always play turn-based combat unless the opponents are very very weak, so I think the criticism was a bit unfair. That said, the combat in Bloodlines was also criticised, so it seems to have been a common theme in Troika's games.
As for the graphics, I think they were just out of date. It came out two years after Planescape: Torment, after all.
