First off if you are reading this you will most definitely read the book of the same title.
The book doesn't translate well into film due to it's short length so there is a lot of padding out of Jonathon just flying around visiting different places but the visuals on show are very good. The animatronics (rememeber they didn't have CGI back in the 70's) are first class and it really does look like live seagulls.
The movie is probably about the right length though at 95 mins perhaps trimming by 10 mins would not have harmed it.
As you'll know it's a feelgood story about the quest to be a better gull and the importance of tolerance and forgiveness.
I was a bit disappointed that one of the KEY SPOKEN LINES in the book was omitted from the script. When the young Jonathon is asked by his mother why he doesn't eat and is all bone and feathers he replies "I don't mind being bone and feathers, Mum. I just want to know what i can do in the air and what i can't, that's all. I just want to know" Considering the key part of the book is that Jonathon forsakes the squabbles and feeding frenzy to learn how to fly properly i would say that line is a pretty important one.
Still it's a decent movie which is pleasant to watch.
