Okay. Read it. Enjoyed it. I'm a huge Witcher fan, though, and not terribly discriminatory in my love of seeing Geralt Do Things. Keep that in mind. If I saw a Geralt cameo in, I dunno, Judge Dredd, I'd giggle happily and immediately up-rate the issue. So, yeah.
That said, let's start with the negatives. The art is good, but not my favourite. It's that "arty" representational style you may be familiar with. rather than being as true-to-life as possible, it's more focussed on impressions. A couple times, faces aren't drawn out. Swords aren't straight. Limbs are, well, yeah. Evocative, not exact. Still good, just not my favourite.
The dialogue is a bit off. Geralt sounds sort of modern-casual Geralt. His intensity is somewhat lacking in speech and word choice. Still acceptable, but jarring from time to time.
It's short - kind of like the last chapter in Witcher 2! AHahahh! Ah. ha. Mutter. Anyway, it went by pretty fast, which is good and bad.
Okay, positives:
I like it a lot! It's Witcher media! It's not terrible! The evocative art gave me that whole murky-forest/dangerous waters feel I find in the books and games. TV series doesn't exist.
Geralt still feels like Geralt. Cynicism, mysterious knowledge, spooky powers and swordmanship. The supporting character also felt quite real and casual-tragic. Life is hard, mistakes are bloody, etc. You know the drill.
A delicious amount of Witcher lore is displayed in a few pages. Bruxia, drowners, grave-hags and more. Felt good, baby. All well-illustrated and written.
Mixed good and bad: made me want to play Witcher 3 so badly it felt like a physical hunger. Time to replay Witcher 2, I guess.
Honestly, I'd wait to buy the graphic novel or buy a few issues all at once. I'll be doing that.
