I've already given my review of Tekken: Bloodline and as someone who played the franchise since the third game which is exactly where the series took place, I'm actually more on the mixed side as whilst I do feel that the fight scenes were good, I can't exactly say the same in regards to the story that felt rushed and the characters did not have enough opportunity to shine within the six episode format.
In addition, I would had like to have them exploit Jin's character further for example how did Jin and Hwoarang's rivalry came to be, his life as a student of Mishima High School and how he and Xiaoyu met.
If there were any other animated series based upon fighting games that I still enjoy to this day, I will say the Virtua Fighter animated series, Street Fighter II V and the Darkstalkers 4-episode OVA are my favourites.
