Nor do I think you (or any of us) are qualified to state "exactly why so few people" watch this.
Why the heck not? Understanding the problems with something is crucial to appreciating the good aspects and understanding why other people might not like it. Just because someone likes something doesn't mean they can't recognize why others might not (heck, I like Den-O, and I fully understand why others don't). I'm a critic, same as everyone else here, that doesn't make me any more or less qualified to analyze it.
Sure, IXA didn't explain it very well, but that doesn't mean other's can't.
Every season after W is a poor imitation of former. Except for Gaim. Wizard indeed tried some different approaches, but ended up being just an another poor copy.
Just look how every season ends. Philip/Ankh/Kengo/Koyomi (every one of them is the most important person in the season) dies, but comes back to life one way or another
That's not being a parody, that's being a rehash (which is certainly a valid complaint, but at least Drive is trying a FEW different things).
