Just watched the movie, and it is pretty much another 1/2 season arc. Similar themes played out (loss of innocence, trauma from goblin exposure, aberration among goblins), but it went down smoothly. Though, as some mentioned, the actual combat scenes were devoid of the tactical nuance the series had up till now. I actually didn't notice until it was pointed out, so its more of a hindsight issue, and didn't bother me during the watch.

ED was nice, too. If you want some more goblin slayer, no reason not to watch the grim dark goblin slayer.
