Another one rated too low, I assume that is due to it - so I read - not being "faithful" to the original television series. I have never watched that so I couldn't judge it in those terms, but as a film I enjoyed it I won't lie.
'Inspector Gadget' is very silly but self-aware, in a similar vein to 'Looney Tunes: Back in Action' and 'The Cat in the Hat'. I enjoyed those two films and, while this isn't as good as those, I liked this enough. I probably wont ever rewatch, but I can see younger audiences finding enjoyment with it.
There aren't, admittedly, any super noteworthy performances here, but that's not to say Matthew Broderick & Co. are bad in this - they give what's necessary. There's a few interesting cameos in there, too.
There are a couple of fairly amusing moments, but it's the dumbness that I think they do well - it's stupid and they know it. Like those other films I mentioned earlier, you're gonna annoy a lot of people by doing that so I can see why this gets hate - I don't think 44% is fair though, but each to their own of course.
