Well I loved 'Final Six' and 'Psychopathy Red' is even better - 'FS' had a Seasons in the Abyss (song) vibe to it, and 'PR' almost has a Reign In Blood (album) feel to it.
As for being uninspired live - they've always been like that....they go on stage, they play their setlist, and they go home. They don't put on a stage show, mainly because they don't need it the vast majority of the time. The only time I can recall seeing a gimmick onstage was when they did the raining blood schtick....it made me cringe, to be honest.
And they don't need to bring anything new to the table at all - they've been doing the same thing since they started, it's got them where they are today and they're gearing up to say goodbye anyway. Why do something new? Stick to what you are good at....they tried something new on Diabolus In Musica which didn't work for a lot of people (not me, I love it) and on God Hates Us All and Christ Illusion there is filler material.
And even though I've seen them live way too many times, I'll still go to see them on the next tour. Not a big fan of stageshow, so going to see 4 blokes go onstage and play appeals a lot more than going to see a flying monkey jump from amp to rafters and then on to Araya's shoulders, just as he screams 'Angel of Death'. (although that would be funny to see)
