 The idea of " fan service " is always a double edged sword . It 's great to see all of the things you may like about a series come together on screen , but it so often works better in theory than in practice . It 's like those giant crossovers that comic books do all the time – where every cool character meets every other cool character . While it 's interesting ( to a degree ) that they 're sharing a page , everybody ends up getting short @-@ shrift .
