Mr Drayton has. The first book is by far the best. The second is ok. The third is shit. Get Berlin Noir my Philip Kerr, superb books.

I'm 3/4 of the way through the first one and similarly struggled with the first half. It gets a lot better and the characters are really the most interesting part. I'd persevere to the end and see what you think after that.

It is only worth it if the story grabs you. I enjoyed all 3 but the key is whether you care why Lisbeth Salander is the way she is. If her character doesn't particularly interest you then it isn't going to be worth the investment of time.

I'd just like to second Mr Drayton's comment on Philip Kerr. Berlin Noir is a classic - Kerr's been criminally overlooked as a writer and Bernie Gunther is his finest creation. Give it a go - you won't be disappointed.

Are great. And, no, the language translation isn't particularly stilted either - it's actually very well done (or so I thought).

Disclaimer: I've read them back-to-back, just around half way through the third.

Stick with them!

I read the first one a couple of weeks ago and the second one on holiday last week. I enjoyed them and plan to read the third, but they're hardly masterpieces.
The second one is well over 500 pages long but still leaves unanswered questions (possible plot spoilers coming up) What happened to the men exposed in the scandal? How is Miriam Wu? Who's idea was it to introduce a professional boxer for unlikely plot reasons? (To be fair, many of the characters seem as surprised by this last one as I was.)
Some of it may be down to the translation. I winced when 'noisome' was used as a synonym for noisy, and I doubt that the same confusion exists in the original Swedish.

doesn't translate very well into English. I've always thought that the Wallander books are very clunky and extremely slow moving. Bit like an old Volvo really.

..is where it's at in Scandinavian crime fiction, (a ten novel series, and all ace). But give Philip Kerr a go first.
