Pros:
Nice mix of throws, some wooded, some mostly open. Good use of what they had to work with.
Course can be split into a front or back 9, in case you have a limited amount of time.
----------
Cons:
What they had to work with wasn't all that much.
If the course gets spotty maintenance, the rough will make it unplayable. (Literally unplayable: there are a lot of thorn bushes in the rough, and lots of rough in the course. If the rough is mowed regularly, it won't be a problem. But only if the rough is kept in check.)
Small parking lot. This shouldn't be a problem most of the time, but it will make club activities difficult.
Google maps sends you to the wrong place on the park. This isn't a fault of the course, but if you're trusting Google to get there, it will send you to the south side of the park, and the parking lot (plus hole 1) is on the west side of the park, off Hohl Road. And hopefully this will get fixed at some point.

Other Thoughts:
As noted earlier, they did very will with what they had, but they didn't start with all that much. There is a decent mix of technical and air-it-out holes, minimal elevation, and essentially no water or other obstacles. There is a fairly good mix of shots, and you don't feel like you're repeating the same hole with minor variations (one problem that many courses like this face).
[-]They used Predator baskets. This was my first time with this basket type, and I noticed that they required a bit more precision; I had a few shots that might have landed in other manufacturer's baskets bounce off the edge. Whether this is a good thing or not, I'll leave up to your judgement.[/-]
The Predator baskets were removed and replaced with more standard baskets. I'm sort of disappointed with that choice, as I felt they gave the course a certain flair.
As mentioned, the real challenge for keeping this course alive is going to be maintenance. This is a very early review (the course has been open less than two weeks), so I don't know what that's going to be like. Greene County Parks and Rec did get a levy passed last year, so theoretically they'll have the funding to keep the rough in check. But if they don't, there are thorn bushes in enough of the rough that this will become unplayable.
[-]Another early issue: the deep wooded holes (12, 13, and 14) have a large number of dead ash trees that are scheduled for removal. Right now, it's hard to throw any distance without a significant amount of luck. However, I doubt this will be an issue lasting past summer of 2017, if it even goes that far. As was mentioned elsewhere, hole 10 currently seems to be in the process of being re-routed, and there's an extra basket at the end of the course that doesn't have a designated tee. Signs are not installed, so I can't judge them yet, nor do I know if they're going to be putting in tee pads. A course map is on the park Facebook page, and is probably a good idea to bring, at least until they get signs and basket toppers (which I've been told will be set to point towards the next tee.)[/-]
This course has aged well. Greene County Parks & Rec did a nice job clearing out the thorn bushes, and they opened most of the fairways on some that needed it. There's still a tall rough, but it gets enough work that you're probably not going spend too much time hunting lost discs. And if you do actually lose a disc, there's a lost & found box in the parking lot, so hopefully someone will drop your disc in there at some point. The signs are very nice, and concrete tees are a nice finishing touch for the park.
The final analysis of this course: it's a nice, solid course that's going to be great for locals, especially given that some of the nearby courses are showing their age and are coming due for either removal or refresh. However, there's nothing in it that would make it a destination course: play it if you're in the area, but don't make a special trip for it.
There is one exceptionally unique hole: hole 10 is a tunnel shot through some tangled trees. Despite tipping in at 117 feet, this is a real hole that has challenge and risk, and despite being deucable, it still feels nice to just hit par on it.
