As much as I like BG1, I can totally understand why people might call the first few hours uninspired. Most of the encounters are just against dudes with regular weapons, and unless you know what you're doing, your only real "tactical" options are probably going to be Imoen's Wand of Magic Missiles, a couple of Larloch's Minor Drains, and Jaheira's Entangle spell (though this one is really good). Somebody new to this might not realize that BG1 is all about disabling spells that allow your characters to attack bad dudes unmolested (i.e. Sleep, Entangle, Horror, Hold, Stinking Cloud), at least in the early game.
The game really starts going in stride after you finish the Nashkel mines and start exploring around for the bandit camp. That's when you start to run into more enemy parties and monsters with more abilities and you actually have a decent repertoire of weapons, spells, items, and abilities. Though I can understand that, in this day and age, with tons of classics/indies/forgotten gems, that grinning and bearing it for hours, without any guarantee of payoff, might be pretty unpalatable.
Icewind Dale was fun, but in retrospect, it really is a lot shoddier designed than BG. Too many dungeons consist of nothing but "big room of monsters", and often those monsters have no abilities but bog standard melee and inflated HP. A lot of the boss fights are pretty lame as well. One is against a powerful breed of demon, that's only strengths lie in being immune to +1 or less weapons at a time when you don't have many of them, and high "combat stats" like HP, armor class, damage bonus, etc. It doesn't compare favorably to BG1 bosses/set piece encounters and even more unfavorably to BG2's excellent encounter ensemble (dig that alliteration, yo).
