You cannot recommend someone to play MotB with all its issues but not recommend someone to play the best mods made for NWN.
I've never finished MoTB because NWN2 is so bad to play.
You are missing out man. There are some UI and gameplay improvement mods, you should try them out, they should make it more bearable.
As for NWN 1, the game is a lot more enjoyable to play, the inventory is a blessing, the controls are responsive, and all in all its simply better in every conceibable way.
The worse part of the game were the god awful OC and the now extremely dated graphics.
Rake well, i dont have a good list on me right now, but you probably should start with Adam Miller modules
Shadowlords, Dreamcatcher and Demon. They are a trilogy with decent to good writing and above all a clever use of scripts that by Demon it just gets downright impressive.
A dance with Rogues is often praised module, adult and with a good amount of C&C, personally i cant recommend it as ive never played it, mainly because it is aimed at female characters.
Penultima is a goofy campaign, pretty interesting world that reminds me a lot of my teenager years of PnP.
The bastard of Kosigan saga has "mature" writting and it definitely succeds at what the witcher tries and fails to do with its setting.
I think you have a remake of the Eye of the beholder that is pretty good, if you arent too much into blooblers you should try it, its been said to be more challenging than the original game.
There are several modules set in ravenloft that do a fairly good job with the setting.
I remember there were a couple of psychological horror ones, they were really good, cant remember the titles tho, so ill get back to you on that.
Because you only handle one character in this game, most of the modules are character and story driven, so a story fag should be right at home. A combat fag can get a lot out of the 3.X modified system, making builds and watching them perform at different levels is fun.
