Good points, and in all fairness I like what they did with DC Universe, obviously with very little money. And most of the theme around the park is pretty light at best, which is fine for a thrill park. The problem I think, has been the schizo way Six Flags has viewed the park over the years. When you go from "extreme" park, to family friendly, back to thrill park. Some theming here, no theming there, this is what you're going to get. The park is in dire need of a clear identity, and they need to wear it with pride. Whatever you're going to do, be the best at it.
You always get the feeling they are one foot in, one foot out all of the time.
Also I see no problem with criticising the park. Sometime I just get tired of the same moaning every year about Scream. Scream is a parking lot coaster...the end.
