Here are the reasons why the UK version is BETTER than the US one:
1. Steve Carell is not convincing. This guy looks as much an office manager as Pamela Anderson does a bookworm in a bookstore.
2. The US series is NOT original. WAY too many parallels between the characters on both series. I own all the UK "The Office" DVD's and have watched them all many times. I watched the US version a couple times with my wife and I'd give all the US characters their British counterparts' names. "Oh, there's Tim and Dawn. ...the big oaf, that's Keith. Yeah, there's Gareth kissing David's ass, etc..." Why watch the watered-down American version that's NOT funny when you can enjoy the hilarious British one with the touching drama added in?
3. Gervais and Merchant knew when to pull the plug on the UK series while the US one has alreadly overstayed its welcome. Face it, offices are not naturally good grounds for comedy and drama (despite the rise in office-based commercials). The UK one focused on developing its characters and plots intelligently and ended it when the story was over. Two complete seasons and a Christmas special...absolutely brilliant. The US version, instead, tries to keep the fire burning, thus dragging rather boring sub-plots and not-so-funny situations out further than they need to. Why Ricky and Stephen haven't tried to accomplish the same thing over here is beyond me. ..but the US is a different market and I'll get into that later.
3.1 On the same note, the UK version is simply better because it was out first. The Tim and Dawn drama was bittersweet and beautiful. The US version is so much a rip-off of the original that it's hard to feel any compassion for the characters within. We know how it's likely to end. (Unless they decide to throw a curveball and do something different with the two pseudo-lovebirds.)
4. The US television market is overall very brainless, much like its viewers. We in America tend to want what's popular and nothing else. This is why there are thirty medical dramas, twenty courtroom dramas and a boatload of reality shows. Taking chances and being different is unheard of here, which is why we tend to pull from what's popular in the UK. We can't create anything new and exciting, so we must "borrow" from those who CAN create something wonderful. This is a problem. The US "...Office" is such a bland, tasteless morsel of what the original was, it's sad that so many people find it to be something else. Steve Carell is no Ricky Gervais.
