Perfect for beginners and intermediate players
Great for working your accuracy in your short game
Good mix of traditional length and short holes
The wooded portion really uses the landscape well in providing some tight fairways especially on hole 9

It does share the land with a playground, tennis ball courts, and a couple little walking paths. Not necessarily a con but just something to keep in mind when it comes to weekends
Small course means crowded on weekends especially with other disc golfers

For what this course is and who it's more targeted for it's a fairly good place. Holes 1-3 get your arm stretched out. 4&5 are a lot more shorter but work your short game especially with the OB behind hole 5. Hole 6 really puts your technique to the test with a rising fairway that flattens out about 120ft from the tee and then dips back down to the basket. Hole 7 plays more favorable towards RHFH players with a downhill shot that ends either 30ft from the creek or up in the trees on the hill. Hole 8 is a short triple mando down the gut with OB down by the creek. Last is hole 9 which also plays a little more favorable towards RHFH players. In the short it's possible to get a birdie but in the long par feels like a birdie.
Keep in mind that there is a playground so there are children that might run out on holes 1,2,3,7, and 8. Be patient and just try to educate other people about the sport. Signs are posted and sure everyone should be reading them but it's a two way street. Another thing to note is typically on weekends the course gets a lot of foot traffic. If you're looking to play here on a weekday your chances are pretty good you'll get through with hardly any hold up.

Let's focus on the positive things about Miller Park shall we? I will be reviewing this from a Disc Golf perspective on the course itself.
First off, the Teepads are very nice for being in such a small park. Some with gravel that looks like it will drain well during rain. Each Hole has a vibrant tee sign with animated fairways and Hole distances as well as a marker for the pin placement. There appears to be 2 pin placements per most of the holes.
The first 3 Holes are in a wide open grassy meadow with mandatory's on each one of them to direct players shots away from potential pedestrians/other players. Holes 4 through 6 play into the wooded area on the hilltop in the park near the small power plant. Holes 4 & 5 are both shorter but technical and Hole 6 is probably rivaled with Hole 9 for the most difficult on the course. Hole 7 shares a tee-pad with Hole 9 and it's possibly one of the widest cement tee-pads on any course I've played - very cool! Hole 8 is a super short pitch with an elevated basket on a slight downhill slope and requires a conservative drive or you could be in the creek at the bottom of the hill. Hole 9 played down a tight fairway with the basket guarded by a many trees, the green is a sloping hill with hard packed dirt allowing any upshot or drive to roll away if it catches an edge. It's probably my favorite Hole on the course for the overall challenge of getting to the green off the tee. Overall I think the course provides a challenging 9 holes to iron out the kinks in your approach game with the opportunity to let loose on quite a few holes.

Now onto the cons of the course. Which it seems most of these prior reviews seem to focus on.
Holes 1 through 3 all use the SAME meadow as their fairway. This easily could cause a logjam on busy days.
Pedestrians also could be an issue if they wander through the fields, but as more people get used to the course being here I think that will diminish over time, (For example, Carmichael Park). Hole 4 and 6 are semi blind shots, if you don't walk up the fairway and check before you throw you could potentially hit a pedestrian. HOWEVER, the majority of Disc Golfers will always check their fairways before just walking up to the tee and throwing blindly. (See Other Thoughts below).
Some could say 7 & 9 sharing a tee-pad is a con, but with the land provided, I don't see this being an issue. What would be an issue is an 8 hole course; so I'm thankful for the creative thought process that went into installing and providing this course to the public!

The park itself has so many different amenities, which some seem to think is a bad thing ? I think this is wonderful, maximizing the use of the small amount of beautiful land they have. I see a lot of resident locals are concerned with pedestrians getting tagged with discs, but I can assure you, there aren't many Disc Golfers out there that aren't aware of the etiquette of the game. To most this may just seem like a leisurely activity we "Disc Golfers" go out and do, but we take our rounds seriously and wouldn't compromise by throwing when a pedestrian is in a potential landing zone. Give the disc golf community a little bit of credit! We take things just as serious as the regular walker, jogger, tennis player, picnic'er, or basketball player that uses the amenities of the park, we're all out there to have fun! Cheer up, grab a disc and get out there and enjoy it!
