I think this is the best Manwha adaptation of all time already. I said it. That's saying a lot.
Solo Levelling had gone above and beyond with the level of care taken through the adaptation - the detailed and calculated story mapping to a screen adaptation has worked excellently - this episode very well demonstrated that.
What was so good about this episode then? Well the answers are obvious: the animation, acting and pace.
Everything in the animation department today was perfect. The fast movements in the first part of the episode seamlessly went to a slower fight dynamic with a steady pace, and when watching the episode, it is very understandable that this was a necessary alteration to make to well-adapt the material, and that the way they did this just makes the episode feel so good to watch.
The voice acting also aids how the episode worked. Sung Jinwoo has been cast perfectly, by an actor well between serious and menacing but also soft - a well-defined, high-quality performance was exactly what was needed (also what Purdy needs at the Superbowl this weekend) and I have to say this was a great showing from the actors. The other actors, friend and foe were excellent and I cannot praise this enough - it is a testimony to a good voice actor when you can feel the emotion even if you don't speak the language they're acting in.
And, finally, the pacing was perfect this episode. Things moved fast but without skipping details - and that is harder said than done - this is a job well done, and we should not neglect the work put into storyboarding episodes because it makes or breaks any episode.
Overall 10/10. No complaints, and a massive bank of praise.
