Masteria Through Time - Blockbuster impressions

So after completing all 4 acts, there is no new boss. Sorry to anyone who was thinking there would be one. Dialogue gets repeated two sometimes three times from an NPC, which is jarring. The only boss you fight is really meh. Oh well you get a big chair and 2 medals that are equal stats but I assume one of them will continue to be released while the other is just from an event.
