I had a great time.
For a veteran anime watcher there will be almost nothing in the entire season that hasn't been seen in other animes: a typical weak teen guy protagonist that mostly coincidentally ends up surrounded by females and the accidental nudity scenes just keep raining all over, there is also of course a great threat that forces the weak teen guy to step up and try to become less weak. This is such a stereotypical ecchi harem setup that it's practically a classic.
While the charactes are a huge parade of stereotypes they still manage to feel very true to their natures and their interactions very often end up being absolutely hilarious. Perhaps an intentional side effect of using large volumes of extremely stereotypical content is that when something completely unexpected happens it has far more impact, often resulting in ridiculously potent comedy.
As for the art and sound it's just quite good and leaning more towards a robust experience than something noteworthy, except just how crazy far some ecchi scenes go. While I'm not giving the show full marks I can't really think of much that could have been done to make it even better, rare situation for someone who loves pointing out flaws!
