Disclaimer: I like Helloween (I have all of their albums), but I'm not a huge fan (meaning: it's not like I was counting down the days to this release)
So, I don't think I'm too affected by sentimental factors (Kiske, Hansen, the good old times etc.). Well, the impression after the first listen is very, VERY positive. This sounds like a very well crafted album, with great songs and melodies. It seems to me it successfully manages to be "classic" and interesting at the same time. Not phoned in at all. Lots to take in, though (just in term of sheer amount of music!), so I'm excited for further listens.
Also agree with the positive comments on Angels (real cool progression in the chorus), and enjoyed the catchiness of Best Time.
