I've recently seen a series of poor productions for kids, so I know for a fact this one is better than many others. The characters are well written and the actors do their job well, both the young ones and the older ones. The story has huge plot holes, just one example is the language the aliens speak, they seem to have trouble with English but on the other hand they speak it among themselves. There're more such goofs but I can't specify without adding spoilers, so I'll just say, that despite this fact, since the characters themselves are real and convincing, the whole thing does work, it's quick enough for the viewers not to notice these inconsistencies and it is funny and exciting. All together - not a bad viewing
