Yeah, I'm playing through Baldur's Gate ( 2, which is ways better than the original, which I already beat ), and it's not this mind-blowingly amazing game. We've come a long way since then, thankfully. DA2 improves on a lot of the problems Origins suffered from with combat. I think it's wrong to say it's not tactical. It's no less tactical than Origins was, that's for sure. It's more fast-paced ( faster, more damaging attacks, more emphasis on AoE, charging out-of-range enemies ), but that's it.
The animations, I agree, are over-the-top. I would've liked for combat to look more realistic. But if that's enough to ruin your experience, then I don't even know what to say.
As for the plot, I disagree there as well. It's far more interesting than DA:O, and doesn't have the standard Bioware structure. It's not the standard epic of the hero saving the world, but rather something more believable. It's not as straight-forward. There are actual peaks and valleys. I do think they could've given you a better sense of progress, but certainly toward the end it feels like much has changed.
There's also a much greater emphasis on characters, both Hawke and the companions. Firstly, Hawke is an actual character with actual emotions and such. I mean, he's not Shepard, but in some ways he's probably the more realistic character. The companions are what really make the game excellent in my eyes, though. Probably for the first time in any game I've played, the party members felt like genuine characters with their own lives, rather than a mob of people who for some strange reason all decide to follow the same person. Hawke is a strong influence on them, certainly, but their lives don't revolve solely around Hawke. Also, you get to have sex with a dusky skinned pirate with excellent taste in jewelry, so ... yeah, that alone would've been enough.
