Transformers: Rise of The Fallen

i just saw this movie 2 days ago. i thought the actions scenes in both movies are very confusing because you cannot tell who is who in the fights, to me its just a mix of metal and sparks. the movie was also a bit to long, it just goes off for 3 hours and then just abruptly stops, strongly hinting a sequel. and what i also dont get about the movie is the fact that the autobots wont leave earth. the so called "all spark" has been found and destroyed but they will not leave. Out of 10 i give it a 6.
