I got back about two hours ago from seeing it. I was really excited as its one of my favourite books of the series and the trailers look fab! I thought it stuck to the story fairly well and had a slightly slower pace than its predecessors, which was refreshing.
However, I do feel that missing out the following was detrimental to the plot:
- Dudley's farewell to Harry
- Kreacher's tale about Regulus and the locket
- Harry's urgency and terror with the Bathilda part when he knows Voldemort is coming
- Harry disarming Malfoy
And the part where the polyjuice potion wears off IN the ministry - it was utterly ridiculous!
However, I did feel that these parts were done very well:
- the chase at the beginning, although it missed out Stan Shunpike
- when Ron rescues Harry and destroys the Horcrux
- the visit to Lovegood (except for the Erumpent Horn)
- Bellatrix's torture of Hermione
- Voldemont claiming the Elder wand was a really good bit to end on
