I start my review by saying this is a very good film but not great in my opinion.
The start is messy and some of the main characters are a little lightweight.
Once it gets going then the pace never lets up and we have some great battle scenes during the last 30/40 mins.
We also have a new droid we can all enjoy, if IMO his one liners are a little too frequent.
Go and see it and enjoy, the old school Star Wars references are worth looking out for.
