Now Do I like it?

Well sorta D&D at this point is a good at a few thing like having more "updates" and having more classes,races,magic,weapons and monsters. I enjoy the simplicityand the extencive journey available.                          
First, the rules are simplified and more consistent. For example, attacks against enemies always mean rolling a d20 and adding your modifier. It doesn't matter if you're hitting with a sword or firing a fireball. You always roll attack rolls. This is a big switch from 3.5 where spells required defenders to roll saving throws while fighters rolled attacks against static defender ACs.

Second, all character classes are fun to play. Such as the cleric (or healer) . Though healing is still a large part of a cleric's job, the cleric can drop a lot of damage and boost a party's effectiveness quite a bit. This is the first D&D cleric that is genuinely fun to play.

Finally, and most importantly, 4th edition is simply more fun to play. Players focus on their powers instead of digging into the minutia of the rules. Fighters have a whole pile of actions to perform while wizards are much more streamlined and focused instead of choosing from hundreds of possible options while the rest of the players look bored.
