I finished the game recently and I'd give it a solid 8/10. It's my 2nd favourite in the series, with some incredible moments and by far the best battle mechanics. Most of the games flaws are small and pretty inconsequential on their own, but taken as a whole the negatives do drag down the experience a bit.
I will say though, the complaints about tutorials and comedy are kinda exagerated. A lot of tutorials are skippable, and their are some great comedy moments. People saying that all the comedy is simply accent based are in my opinion, completely wrong.
Bottom line, if you liked BiS, you'll this as it is very similar in structure and design, with a lot of improvements. If you hated BiS like I did (couldn't even finish it), you'll really like Dream Team because it fixes the majority of flaws that BiS had.
