Pros:
Do you live in Boston? You don't have to drive an hour to play a round anymore!
The course does have some decent variety of holes, including some open holes, two wooded holes, and it does use the mild elevation changes well.
I liked holes 1, 2, and 9, which play near (but not too near) some buildings along an embankment and through a few trees. It felt collegiate.
Navigation here wasn't too bad with the aid of the map on this site.
Cons:
There are no tees, just small stakes in the ground. The baskets are just practice baskets, not attached to anything, and could be stolen. Secure those things!
Holes 3 and 6 included about every design flaw you could think of. Throwing over a field that will be regularly used by other sporting events? Check. Boring wide open design? Check. Two parallel fairways where people are basically throwing at each other? Check. I didn't get to play either of them due to the lacrosse games going on.
Holes 1 and 9 have fairways that cross each other, another unsafe design feature.
The two wooded holes do force accuracy but aren't unreasonably long; those are good things. I do wish the rough wasn't so rough with weeds and what not. You could definitely lose a disc here. So while 7 of the holes are pretty rec friendly, these two aren't as much.
Other Thoughts:
First of all, let me congratulate whoever got this course in. I wish there had been more options close by when I lived in Newton. And not every course needs to be Maple Hill. Sometimes it's great to have a place to play a quick round.
This place has some potential for sure, but the design needs to be changed in a major way. These aren't meant to be snobby criticisms; if someone gets hit in the face with a disc, this course will be gone immediately, so I hope they design the course so that doesn't happen. Stay away from the soccer/lacrosse fields, don't cross fairways, but otherwise design some holes more like the wooded ones and 1, 2, and 9.
