Gekisou Sentai Carranger is one if not the most funneh sentai evahh! Since this series is a parody of sentai itself the humor in this series are ridiculous and outright weird at times so If comedy and silliness borders to weirdness is not your thing don't watch it but if you like comedy and all the Japanese silliness you prolly enjoy this series.
I find it funny that the monster needs to eat Japanese food/sweets (Can't remember) in order for them to grow in giant size but only if the food/sweets are bought from the specialty shops and not supermarket ones lol.
