Is is the kind of anime with a main character who starts off very weak and evolves, but besides that, Ragna also has a purpose from the beginning for which he fights.
In my opinion, Ragna Crimson has a quite good and detailed world, from desolate places and ruined cities to ancient temples or feudal kingdoms, it's like a Kinder egg with surprises. The author has integrated politics quite well with magic and mythology, which are quite important aspects in Ragna Crimson, and offers a broader perspective on the world.
The characters in Ragna Crimson are VERY STRONG, why do I say that? For me, it was enough to see Crimson wielding a weapon around and it made me believe that she's quite strong and carries the entire series, just kidding... the characters are quite well-developed, and they have their own motivations or aspirations. Ragna has several "inner" struggles, so to speak, and constantly matures. His adventure, it's not just about fighting dragons, but he also has a struggle with his own nature and the questions that plague him. On the other hand, Crimson, the other protagonist, is a mysterious character who gives off a unique aura. Her relationship with Ragna is a very complex and dynamic one.
The rest of the characters are interesting too, from loyal allies to charismatic enemies, each character has something unique.
The animation in Ragna Crimson is not very special, it's a 6-7 of 10 (10/10 , like Bleach TYBW/Fate), but the landscapes and fight scenes are very well done, there are a few specific moments for an MC that are like masterpieces. The soundtrack is impressive, and there are also very good orchestral pieces alongside the classic ones heard in any anime, the voice actors did wonderfully, and I felt every emotion they tried to convey.
In my opinion, Ragna Crimson is an anime worth watching, for a seasoned viewer like me, it was something new because it has enough "troll" moments that pleasantly surprised me, and I didn't saw the same reheated soup in a universe with dragons
