Nope, Anathema was never finished for me, maybe we had to find him in town or do something else afterwards, maybe once we entered the Tomb of the Divine (and turned back after reaching the point of no return), though I kinda doubt it.
The final boss fight was deceptively easy, all you had to do was kill Braccus and bam it's over. Though, if you do it while anyone is dead, they stay dead so you better resurrect them before ending or else you don't get their dialogue.
Yeah, I feel like the Nameless Isle wasn't terrible, it served as a good transition point, and was rather interestingly designed. But, I feel like Arx just wasn't a good ending chapter. The final fight was decent, as was Lohsee's singing once you unlock it after killing the Demon, but still.
