Amazon's (AMZN +1.3%) first original content series aimed at children debuts today on Prime Instant Video.
Tumble Leaf is available for streaming at no cost to Prime members.
Initial anecdotal reviews on the series are mixed.
What to watch: Amazon faces a bit of an uphill battle by trying to create fresh characters - instead of relying on licensing from Disney, DreamWorks Animation, or Warner Bros. like Netflix. But the company also saves on the cost side and has vast data mining capabilities to quickly adapt programming to consumer tastes.
