The movie definitely could be better, however, it could be worse as well. It seems to me that the main nuance of the picture, constraining it in a lot of aspects is it's rating, and that looks like creators were trying their best to make something good for the given auditory. So, they achived some goals - though all plots are enough predictable and silly, there are some good ideas in them which could be useful for the youngest generations as well as for the more mature ones who could once more think about such things.
However, I wouldn't watch this movie again because it does not present a unique shape of visual expression and as a result doesn't differ from a large set of Russian movies I've seen previously. Despite said upper, there were some moments which were somewhat hard to predict and match with previous experiences so it shouldn't be forgot to point that out.
In conclusion, I'd like to say that you should watch this movie just if you've got a desire and possibility to watch something with your family, but not more than that - this is not intended for other purposes, which with higher quality have been served by another examples.
