Pros:
Nicely situated beside the Missouri River, English Landing is a course for all skill levels with some technical shots, some long holes, and good maintenance. Two holes were installed recently that replaced what were two of the worst holes. Navigation is straightforward, and it's nearly impossible to lose a disc.
There's surprisingly a lot of distance here. There are opportunities for some really spicy par 3's for long throwers, and par 4's for intermediate players. The distance balance is also present here. Not only is there variety in distance, the shorter holes are generally much more technical than the longer ones. While there aren't a ton of trees, there are some on all the long holes, and hitting an early one will put you in real danger.
Speaking of trees, they're mostly really tall. They help with safety since it's basically never good to throw over the walking paths, and there aren't any over the top lines. There are some shorter trees on a few holes, but even before they grow up, they give you the chance to take some really aggressive lines.
Cons:
No elevation change whatsoever. While the course isn't ever boring, there are some holes that are far worse than others, that could use a little elevation change. Hole 9 is the main example, being the only completely open hole on the course, but especially on a nine-hole course, the variety starts to not be there when you're never throwing up or down.
While there are plenty of trees, there are a lot of holes you can take pretty much any line on. Especially if you can throw really far, a simple hyzer play, regardless of how you throw, may often be the correct line. There are a few exceptions (holes 1 and 6, which are the two shortest holes), but even just a few more trees would help at times.
While the new holes helped a lot, there are some obvious issues. Some of the tee signs are now out of date, and they weren't much good to begin with. The baskets aren't very good. The teepads, which are natural, probably used to be fine, but now they're rather uneven (some are concrete, but only around half of them).
Walking paths are nearby on a few holes, I mean, every hole, and while they're mostly easy to avoid, disc could go the wrong way after hitting a tree. The park is very busy in general, which isn't a problem, but it there is the possibilities of non-discers on the course. Finally, expect to hear a train at least twice a round.
Other Thoughts:
While this isn't a course I would imagine myself coming back to regularly, it's certainly a fun play and has some replayability. New tees would help this course improve the most, as there isn't any more room in the park to expand to and no opportunities for better hole design.
