Yeah, definitely underrated.
A 0/2 for G would be fair. A 0/3 for G would be better than fair. A 0/3 with Reach for G would be great. And Defender on a zero power creature is practical negligible.
Really, compared to the alternative cheap plant blockers, it definitely has it's place.
When a deck is already ramped up with better, more specialized mana accelerators like Birds of Paradise or Bloom Tender, spending 1G on a Vine Trellis seems a waste of mana. In the thick of it, a 1-drop Reach blocker can easily save you the game from your opponent's super-buffed flyer. Plus, if your deck makes use of sacrifices, G is much more manageable and repeatable cost than 1G.
If you're running a Defender deck, use Overgrown Battlement.
If you're running an older deck that needs draw power, use Wall of Blossoms.
Otherwise, if you want a disposable blocker with Reach, use Wall of Vines, or perhaps better, Traproot Kami/... (see all)

This card was a great role player in my 
Metalcraft Genesis Wave deck. Using Cathedral Membrane, Wall of Tanglecord and Gargoyle Sentinel I'd ramp into a huge Wave and win with Ezuri's Brigade. Whoo! Lol

I prefer Tinder Wall instead of this, but with reach? not bad for a defensive one drop. Definitely helps fill in the weaknesses in green VS. Fliers. still, don't rely on it too much.

Off the top of my head I can think of maybe 6 spiders that do a better job than this mass of twigs. If anything this card seems more like a sideboard in case of encountering a player trying to drown you in bird tokens.

It's just so CUTE!
This is what Wall of Wood should have been all along.

The people choose Taproot Kami. I personally am a big fan of Wall of Vines. It gives Wall of Wood a little extra something.
