MTB videos peaked with the Earthed series, since then everything went downhill (no pun intened). Earthed really had the "cool" factor, showing riding at it's rawest all the way up to the top level world champs. No un-nessacary equipment, just cool shots that make me feel like I'm there myself.
Where The Trail ends really annoyed me. I thought it came across a bit patronising and the riding was good, but it never made me go "wow". Same with Life Cycles.....too much work on the shots rather than capturing the fun and thrill of riding. Again I never really went "wow" when watching it and I was kind of glad when it ended.
