Watch the series instead.
Look I'm a fan, I also never write reviews BUT the consolidation of the series into this one movie (albeit there's another to come) feels rushed and does not do service to the character development we see in the series.
As a result I did not feel very emotionally vested in the characters (and I already know them!).
The CG spit polish is well integrated and unobtrusive but at the same time it makes you feel a bit cheated because it doesn't add any significant umph to the shots.
