ABOUT MONKEYS

hello guys, did you know that there is more to a monkey than a "cheeky monkey"? Well, I have a new task for you (film reviews in the post below are still welcome, though :-))
Here's a list of expressions containing the word "monkey". Choose one (only one, to give other people the chance to do their own research) and explain its meaning:

1- to monkey around
2-monkey business
3-to have a monkey on one's back
4- monkey wrench

WRITE A FILM REVIEW

Hello boys and girls, a new post for you (both those who are through with the course and those who are still having exams).
I thought it would be interesting if you wrote a short review of a recent film (perhaps new releases) that you have seen (and discuss it with other mates who have also seen it)....here's an outline of how your review should be written:
1) brief summary (2 lines)
2) state your opinion of the movie (strengths and weaknesses)
3)What characters did you most identify with?(why?)
4) So, do you recommend it or not?

well then...who's going to kick off..? ;-)
