Critics and local observers have expressed caution regarding the proposed Dragon Ball theme park, citing concerns over the project's long-term viability and the potential for significant environmental and social disruption. The history of the Mirapolis site itself serves as a stark warning; despite high ambitions in the 1980s, the park failed within four years due to poor attendance and financial mismanagement. Skeptics argue that a billion-euro investment does not guarantee success if the project does not align with the specific needs and cultural expectations of the local population.
Beyond the financial risks, there are serious concerns regarding infrastructure and land-use planning. The area near Cergy is already subject to significant traffic and transit pressures. A project of this magnitude would require massive upgrades to road networks and public transportation, which could place an undue burden on local taxpayers and disrupt the daily lives of residents. Critics also question the reliance on a single, foreign-backed entity for such a large-scale development, noting that if the project fails, the local community could be left with another massive, abandoned facility to manage.
Finally, some observers argue that the focus should be on sustainable, community-oriented development rather than massive, commercialized theme parks. There is a preference among some local stakeholders for projects that provide public value, such as natural spaces or community centers, rather than a niche entertainment complex that may cater primarily to international tourists. Without transparent planning and clear guarantees regarding the project's impact on the local environment and economy, many remain wary of the potential for this ambitious plan to falter just as its predecessor did.
