Jurassic World - Trailer

Have any of you been to the new Jurassic Park yet? it's already part 4 and I'm really wondering if the movie is any good. after all, I loved the first parts as a little boy, but I don't feel like spending a lot of money at the cinema for a mediocre movie. the trailer certainly isn't bad, but if we're honest, they always look good across the board. I thought they were really exciting back then and would be extremely happy if the last part was anywhere near as good as the ones I saw back then... :DAlso? Can someone give me some feedback? https://www.youtube.com/watch?v=YCL4nsI-ExA
