I can definitely see it being exhausting as a whole. I'd say maybe take the first six songs on their own and then take the epic on its own at first?
However there's no getting around this being pretty much genre-defined prog metal, aside from the somewhat different approach on vocal melodies. I'd say they're one of the better bands in the genre, but if you're someone who isn't too interested in Dream Theater-style music anymore, I'm not sure it'll do much for you besides maybe liking a couple of the songs.
