beyblade had carlos and kai on the first ep
metal saga had the face hunters and kyoya in the first ep.
burst only showed some rivals we will get who will be the villan for like 5 eps
so burst didnt have a big bad guy on the first ep but lets see the plot points of the first ep of each
beyblade, introduced us to tyson and max and kai.they just beybattle in a roof and fight carlos and talked alittle about the bitbeast.
metal saga showed us the face hunters along benkei kyoya and gingka and kenta they just fought each other. and talked abit about blader spirit
as for burst it showed us 5 bladers, valt, shuu, ragnarok, deathsyther and kerbeus dudes. it showed us some back story about valt and shuu. it showed us valts family and home.
so its following a verry different formula so far with the story. i still think they will make something happen. but for now i think they are just introducing us to the characters. as for a show its self i found it really fun. its got great animation, the intro looked great, and it had a fun feel over all. as for a beyblade series so far i like it. the metal saga was super fantasy style and it was great!. the original was alittle more realistic with some fantasy elements. so far burst seems to be the most realistic, but that can totaly change i mean, look at the first ep of the metal saga, it looked very realistic in a way then by ep 3 we saw it start to change. so who knows burst might change. but like i said over all it was a fun ep. so i dont know why some people are complaining when its just the FIRST ep. ya its not as "full" as the other first eps we had but its alittle more personal.
