Transformers Age of Extinction

you really need to be a transformers fan or less than 7 years old to enjoy this. previous films were better. i think Michael Bay was just going through the
motions . Tessa  Yeager (Nicola Peltz), the girl just seemed token glamour.
Given she'd been brought up by an"inventor" Cade Yeager (Mark Walhberg) I expected more techno savvy from her but ended up damsel in distress and lots of screaming .
I've known transformers 30 yrs, nice to see the Dinobots appear though no explanation of them to the masses! yes i expected the story to be evolving over 4 films but the back story was very thin  and disappointing. My favourite character was Joshua Joyce (Stanley Tucci ). 3* (2* if you're not a Transformers fan).
