We can pretend those things matter of course. But the only things that really matter in that fight are the valve, blunt damage and exploiting the AI. A level 1 character with a club can beat him to death once you learn how to exploit the required sequence. A small level 1 party beating up an adamantine golem is throwing D&D rules out the window.
It was definitely not a hard fight but it's one of the few fights when I had my main knocked unconscious (the golem was moving faster than I calculated; things can go wrong in this fight as well). The golem was just an unintelligent machine so I would not worry too much about the fact it was exploitable. Not every encounter can be won with a brute force. Personally, I enjoyed it. Not my favorite fight but it was not bad. Once again, it is an optional boss.
@MrToucan plenty of things to deal with in Baldur's Gate. I can certainly think of a certain vampire lord and his lackeys, for example. I do not think we will be let down with the main story arcs.

Also, timing hits with the forge showcases the weakness of a turn based system. If they have enough movement to pass through the threat area, you simply can't do it. I'm not sure it's a brilliant idea to include stuff like that.
Maybe. The turn based system makes an encounter more manageable and that's the reason it is used on a tabletop. In a lot of games as well. You can still manage to pull it off, though.
The crafted adamantine equipment is worse than the +1 armor the very first vendors you find have available. It is very lackluster to craft worse armor at the end of the game than what you buy in the beginning.
You've beaten me here. I admit it. I thought they are at least +1 armor in addition to being adamantine. I hope this changes by the time the game is fully released. You know what... Shadowheart looked good in her new armor!
