I respect your opinion but this is just my thought on the power up shinra got while fighting. We clearly saw that he wasn't wining against his brother because he had the blessing but then because of the adolla link, he was able to connect to him and gain the blessing indirectly which boosted his power too. And I'm not sure which fight scene you were talking about but in all of the scenes shinra is already powerful but he gets nervous so his teammates have to calm him down by talking to him. And about the fan service... Well there's just one character maki (I think this was her name lulz already forgot it) who is the fan service and for me she didn't really affect the anime that much. She isn't the main character, she isn't that prominent, her presence doesn't really affects the scenes other than one fight scene with the member of the 1st squad who almost killed her. So overall it wasn't too much to affect the general enjoyment of the anime and for me specially the fights more than made up for it. Specially the fight of the captain of the 7th squad. Maybe it makes me a simpleton but whatever lol. And its just my opinion. Thanx for reading.
