I think that audience word of mouth will carry this movie farther then any other summer film this year. So see the movie. See it with friends, in a crowded theatre with surround sound. Its kind of fun to hear and see reactions for something we had already been a fan of for up to decades now. Bay and company have been vindicated and when they said "wait and see", they where not kidding.
Final note, I sat through the credits and their are only 3 sequences that occur during the credits, none after. The last involves a Transformers. Once see that, free to go unless just like reading the credits.
Update: For the United Kingdom, they have 25 long days and Japan another 30 so the countdown begins again for the UK.
