I'm rounding up from 3.5 stars
It was definitely a solid ending to the series.
I thought it started off a bit rocky, it was jumbled and jumping all over the place. It just didn't flow very well to me. I know it was supposed to show a lot going on in a short amount of time but it felt rushed.
Once they got to the meat of the story it got a lot better and was pretty cool.
The end was rather unnecessary but I get why he wrapped it up the way he did.
Overall, not a bad ending to the series but this definitely wasn't as good as the first two were for me.
