NGNL has some fan service, I wouldn't say it's over the top, but if you hate fan service it might make you think less of the anime. The plot was good enough to keep me watching without getting bored. It has decent comedy in the right places. There are parts that are suppose to be serious(?) that seem out of place, but they're not often.
It doesn't feel that rushed compared to other 12 Ep seasons, but it definitely should've had 15-20 in my opinion.
Overall it's a good anime that shouldn't be taken too seriously.
