I don't think Dudley is anywhere near where the finished product should have been. I think the land and Dudley gets a little too much criticism though, probably since people know that both were a result of Universal going too quick >wink<. I think the whole Popeye corner is very well done, including its queue. Dudley's ride profile is great, the showbuilding is great, the queue is great. That's where it stops. The logs have become worse, the upkeep is completely subpar, and the weak show sets don't even meet lowered expectations (especially in the sound engineering area).
The main street for Toon Lagoon is well done for what resources and IP they had at the time. I think the shops and restaurants are very nice. It is a nice sensory break from the hyper MSHI and/or the dense JP. So, in that sense I think the design sensibilities came out with that corridor, again, with what resources and time they had to work with. It is a step up from what DCA 1.0 was, and for less money. It will always be ripe for an update.
You know what my favorite part of Toon Lagoon is? What I can just sit for hours doing? Standing on the Dudley bridge at the water cannons with three or four rolls of quarters. Great breeze, Mellow Yellow nearby, and a lot of laughter. Sometimes it is my favorite way to kill a couple hours. Some of the best positioned water jets in any park.
