I am a super young guy and I like a lot of stuff that people on this site generally deride as vapid and banal, so keep that in mind. I really enjoyed Pillars. It wasn't the top of the class or anything. It was a couple years ago where I played BG1, then BG2, then Pillars all in a row, all for the first time (for reference, I was a toddler when BG1 released). I liked BG1 the most of the three but still greatly enjoyed both BG2 and Pillars. The spirit of the games all felt very similar to me, and I wanted to play Pillars after finishing Throne of Bhaal because I was very taken with the RTwP gameplay. (Throne of Bhaal sucks, btw, did not care for it at all, minus the HLA which were kind of cool, but not enough cool to discount how trash I thought the rest of ToB was)
My point is this: Pillars is a more than decent game. Yes it has its issues, but dissecting a game to the autistic level that many on this site do will sap enjoyment from almost any of them. There is a lot of charm to PoE. There are also a number of issues. I think it just depends on if you're willing to let yourself get absorbed into the game and its setting.
