In the early days of Bay's career, films such as 'Bad Boys', 'The Rock' and 'Armageddon' were of course "leave-your-brain-at-the-door, testosterone packed" action flicks - but they still had charm that made them bearable. These days Bay just makes films that are god awful. This is probably the worst of them (or at least, the worst that I've seen or care to remember), and that's a shame because the original was actually quite good. Whether or not it deserved or needed a sequel is questionable.
Smith & Lawrence's chemistry has evaporated over the years revealing exactly how much talent they have (i.e. none) and everything Bay has done in this film opens alot up for scrutiny.
