    println rev$i.email

    Not that dynamic is groovy. This not a valid groovy syntax.
    Put those object, you want to access in later in your code,in a collection. 

    def revs = []
revs << new Review(email:'one@homail.com',content:'i really like it')
revs << new Review(email:'two@homail.com',content:'i really like it')
revs << new Review(email:'three@homail.com',content:'i really like it')
revs << new Review(email:'four@homail.com',content:'i really like it')

    then you will have references to them:

    revs.each{
   println it.email
}
