It's a fun and thoughtful series. I can't say that you won't like it, because you will...and you will also hate the way it coughs and weezes to the finish line and pretty much ruins any dramatic tension that it spent twelve years building up. But those first 12 years...really a fun ride. Can't take that away.
Naruto is like a longer version of Bleach that way. The author clearly had a long term plan but somewhere along the line realized he had no plan for an ending and started making stuff up on the fly.
If you do decide to watch it (very, very big task) save yourself some time and skip the filler arcs. They're both notoriously terrible and equally boring. I don't care if they're ten episodes or 76 (seriously, in Naruto there is actually 76 straight episodes of pointless filler spanning 1 1/2 years). Skip right past them, do not even acknowledge they exist. They do not affect the story one bit, so you won't miss anything important.
Here's a guide. A bit outdated, but it gets you started.
