Personally, I liked it and could see past the odd cheesy bits, but I can also see why some would think it falls short. There is a very E.T. childlike feel to the film, which is hardly surprising as the lead characters are kids. There is also the Stand By Me coming of age aspect. All this is wrapped up with a bow made of some fantastic visual effects.
Cool film, but difficult to pinpoint the target audience they had in mind (in my opinion). I’m sure over the next few years I will watch and enjoy it several times, but I don’t think I will be buying it.
