That is not bad! Yeah now FUNi in the UK I can legally check shows out before watching (I am more of a dub guy).I couldn't get into it that much, ended up checking out where the series went from where the second series left off and the ending just frustrated me.
Now I have a Crunchyroll subscription I'll be more likely to check a series out before buying should I want to acquire it. I've been lucky so far with my purchases, and should I really dislike a series I can always sell it off. Thankfully I haven't spent more than £20 on a title I didn't like so it wasn't too frustrating an experience.
And re: Haganai, yeah I tend to forget about the second season when talking about it should have noted just the first season, the second season isn't great the ending to it sucks and the original source material gets even worse! But still the great first season exists and that is a ok!
