I believe that the Sword Art Online anime franchise is an exciting and entertaining series that explores the potential dangers and consequences of virtual reality technology. The character development and storylines are well developed, and the action scenes are intense and engaging. However, some of the later seasons and spin-offs have been criticized for their hurried pace and lack of story depth. Overall, I think Sword Art Online is a strong franchise that raises thought provoking questions about the future of technology.
I watched the first season when it first came out. During this time, several more seasons of Alicization, Gun game online and etc. have been released. Yes, the first season turned out to be legendary, from the mysterious beta tester Kirito to the black swordsman, he saw his acquaintance with Asuna and the birth of their life together. Rescue of other virtual worlds, epic battles, as well as the death of friends. All this you will see if you watch this legendary and one of the best anime franchises, although subsequent seasons are not as good as the first. I don't want to spoil too much so look ahead. Thank you for your attention.
