Related to the below, but not as detailed; everything in both series is canon, but is subject to Broad Strokes. Most of the Rule of Cool and Rule of Funny is edited out, but things like Haruhi's Charles Atlas Superpower dodgeball game in episode 5, Haruhi's scavenger hunt in episode 7, Yuki's omnipresent geekiness, and even, perhaps, the resurrected chibi Asakura, are canon to the orignal series, but Played for Laughs in this version of the series. Churuya-san is mostly not canon, although things like her love of smoked cheese and perhaps Ashakura's crush on Kyon might be canon.
