I think if you really, really, really temper your expectations, there's quite a bit to be pleased about. The investments and improvements have been steady and positive. While the additions have been extremely conservative, I think the park is on the rise. A 24% increase in rides given is impressive, and I'd bet that there's a positive correlation to increased margins. I also think the seasonal events are a good, cheap way to increase revenue. Anecdotally, HitP seemed like a huge hit! I'll be interested to see the park's financials when the 2017 report comes out.
Maybe if they keep this up, we'll see a new coaster within 5 years. But I doubt we'll ever see a path connecting Coyote Creek and Gotham City.
A bathroom and some trees over by SRoS and Batwing would be amazing though.
