Pros:
Lakeside Hills, recently redesigned, has a great mix of short and long holes, par 3 and 4, and great hill usage. The uphill holes (1, 4, 8, and 10) are some of my favorite uphill holes I've ever played, since those are usually filler holes on other courses.
Tee pads, signs, and baskets are good quality. There's good signage to help you find the next tee. Rocks serve as benches on roughly half the holes, and there's a new wooden staircase to help you get to hole 4's tee, an area that is often muddy.
The only holes that are heavily wooded, holes 4, 5, and somewhat 18 and 10, are really challenging and provide a nice variety away from the openness of everything else. But maybe 4 is a little too tight, though two great shots will certainly get you to the long pin.
Most holes have some kind of opportunity to air it out, while still having some danger. Holes 3, 13, and 16 have a low ceiling off the tee, 1, 16, and 17 have OB, and the hills provide danger of sailing long or having awkward putts. Hole 9 is a far downhill shot like none other due to trees forcing a higher line than would be optimal. Hole 18 has a weird line into the long position, but a good drive will have a somewhat open approach.
On the longer holes, there's still some variation and obstacles to avoid. Unless you're able to place your disc in the same spot off the tee, approaches will vary wildly from round to round. A small difference in drives can result in different angles to the basket for your second shot. So even if you won't be hitting any trees off the tee, there is still reason to put the disc on a certain side of the fairway.
Cons:
Most holes, including pretty much every hole on the back 9, play directly either north or south. It gets repetitive, especially when there is little variance with wind direction. Speaking of wind, parts of this course are pretty elevated, so there's a lot of wind sometimes.
A few of the par 4's don't quite stand up to standard. They're still fun and challenging, but a long shot can get pretty far down there. At the same time, there are a couple of par 3's that play as two-shot holes, despite being labeled otherwise. As a result, several holes will have pins whose pars don't make sense for several skill levels.
There's some opportunity for mud after rains, but grass has grown on the new hills in the last year, which should keep everything mostly dry.
A handful of holes seem like filler to me. Hole 2 is just straight uphill and pretty boring, holes 6 and 7 are flat and a little boring, and hole 15 is unexciting as well. I don't think any of those add anything to the course. A few of the open holes on the back nine can start to get repetitive, although they do all have a different fairway shape to them. I'm also personally not a fan of hole 16, due to the low ceiling, then odd upslope. It's unique, but in a bad way in my opinion.
Other Thoughts:
This course has finally recovered from the redesign when the rest of the park was improved and a new road ruined a couple of the former holes. Only holes 1, 9, and 10 are the same as the original layout. With signs and grass, it is in good condition. However, I think there was some missed opportunity to have some really awesome holes, even a par 5 or two. There's certainly the land for it, especially if the pond near hole 3 was available.
There's a path running through parts of the course, mainly coming into play on holes 1, 3, and 17. Make sure to avoid other park users, but the path does make a challenging OB element on those holes, especially since 1 and 3 have woods on the opposite side of the fairway as the path. Fortunately, it's easy to see if there's anyone coming on all those holes.
I really like this course. I think it's one of the more challenging and accessible long, open courses out there while still managing to give a different experience every time. This is certainly a round down to get to a 4.0 review for me.
