 Weasel words 

""''Many speculated that Green Day had painted themselves into a corner and would be unable to return to punk music. Nonetheless, many fans hold this album in high regard as being creative, experimental, and overall musically successful.""

The words ""many speculated"" are used to justify a personal opinion in the following two sentences. It would be better to quote a specific source that criticises the band and then a source that highly rates the album."
