I would rate it 4.7 but this the reason why cause a certain magical index is good cause its perfectly blends science and magic and has a lot of likable characters and sometime have comedy good fight scene and a good plot the cons are that it gets better on and you will need to learn in which order to watch it in Its a little bit slow but if u like anime's that have logic in them and not a OP protagonist but in a certain scientific accelerator he's OP tho and I guess misaka mikoto is OP but that's just my opinion.
