First of all I have to say that I never was a big fan of the original TV-series, but the main reason for this is the fact that I was born in the mid 80's and thus my cartoon heroes were those who came after Wickie. Thus I went into the movie without any expectations and ended up being pleasantly surprised.
The story is neither overly inventive nor epic, but there's always enough happening to keep the viewer interested.
The movie had plenty of fun moments, I couldn't help noticing that it's mostly targeted at the younger generation but there are also a few mature references. Altogether anyone who has a good relationship with their inner child should have a few good laughs throughout the playtime.
The cast is mostly unknown (at least to me since I don't watch that many German productions) but excellent. Almost every character has a striking resemblance to his or her cartoon counterpart and the acting is decent.
Yet again I have to bow in front of Bully Herbig when it comes to production value. The movie looks and sounds fantastic, if it had been a high-budget Hollywood production there probably wouldn't have been too much of a difference to the product at hand (Apart from the addition of some overdone special FX). The music composer Ralf Wengenmayr did an excellent job of working the original melodies into the score as well as adding some new ones which really matched the movie's mood.
Most people, Wickie fan or not, should enjoy it.
