Waltorious: The usual reason given is that it's not particularly interactive. You basically click and watch Geralt do stuff, and it doesn't feel like you're actually doing it yourself. Also, people playing on the normal and easy difficulty modes will probably find the combat quite easy as well. So, for some people, they feel like they just click the mouse at a prompt and are otherwise basically watching a movie.
I did not feel this way; I liked the combat and the rest of the game, but I can understand the criticism.
I'm looking forward to the Witcher 2 though, as pretty much everyone seems to think the combat is improved.
By tedious I mean difficult to learn and succeed with and such. He seems to want it to be easy so he never messes up which annoys me. And it contradicts his complaint about monotony.
That's a valid complaint, but like yourself I love it anyway.
It is and isn't...you can click like crazy and pull off combos just fine, which is awful...but you don't have to and I found myself playing more like TW1, but with all the changes and enhancements. Also it gets pretty damn easy for awhile (even on Hard) so combat isn't as satisfying. Regardless, it's an amazing game.
