Say "yes" to Zooey Deschanel. No longer stuck playing the star's oddball friend, she graduates to a lead role without losing any of the quirkiness that made her Hollywood's go-to-girl for oddball sidekicks. Whether teaching a jogging-photography class, getting existential on stage with her avant-garde performance group Munchausen By Proxy, or even just riding a scooter, her Allison fizzes up every scene with a wacky comic charm that's simply irresistible. She's Juno all growed up.

Say "yes" to the promise of 'Yes Man' — the idea of someone agreeing to every question should be enough to kick some life into the tired romantic comedy genre; the first impressions of Jim Carrey's miserable bank employee Carl, turning down social invitations as often as he does loan applications, are a reminder of his surprisingly genius performance in 'Eternal Sunshine Of The Spotless Mind'.

But say "no" to just about everything that follows. After Carl attends one of those self-motivation seminars — think Dr Phil on speed — he feels obliged to say yes to everything. Learn to speak Korean? Yup. Organise a bridal shower? You bet. Take flying lessons? Yes, please. Find a Middle Eastern bride on the internet? Why certainly. Accept the sexual advances of his elderly neighbour? Come on, what do you think?

It's not just his sex life that improves, though. So, inexplicably, does his luck. By saying yes to everything, everything suddenly goes his way. And, to celebrate, Carrey brings on the crazy. Clearly trying to distance himself from his terribly unfunny turn in the unintentionally hilarious thriller 'The Number 23', he resorts to the "rubber-faced" goofing around of the 'Ace Ventura' years.

But behaviour that would usually scare off even someone as spontaneously unpredictable as Allison predictably leads to love and 'Yes Man' settles into familiar romcom conventions — Carrey's goofing about and Deschanel's idiosyncrasies notwithstanding.

Just say "no".
