Opinions on Mareel are split amongst many in Shetland Motivations for building Mareel include the development of the music, film and
creative industries, tourism, educational opportunities, job creation and the provision of leisure and education facilities for the community, particularly young people. Some local businesses, particularly Lerwick pub and night club owners via the Shetland Licensed Trade Association, claimed that Mareel would negatively affect their profits and an anonymous
State Aid complaint was submitted to the
European Commission on 17 July 2008. Shetland Arts countered these claims by providing evidence that Mareel would "generate activity and vitality into the night-time economy of Lerwick, to the benefit of all including the local hoteliers, publicans and restaurants". The State Aid complaint was not upheld. Another source of concern was Mareel's business plan which detractors claim is unrealistic, particularly in terms of revenue raised from sales at the cafe bar. However, the business plan has been reviewed and approved by funders.
Highlands and Islands Enterprise commissioned an Economic Impact Study which highlighted outcomes including the creation of 52 jobs and a positive impact on population retention of young people – an HIE Youth Migration Study identified the "creative industries as one of the most important sectors in encouraging young people to stay in or return to Shetland." Some detractors have claimed that the capital funds allocated to Mareel would have better been spent on other projects, such as to avert the closure of rural schools, apparently under the misapprehension that the funders' capital could have been diverted to bail out the Shetland Islands Council Education revenue budget which had been overspent for many years. ==Shetland Islands Council support==
