Mixed feelings about this one...
My initial impressions with TF2 were rather limited, but the cartoony appearence was interesting to say the least. However, after both Beta Testing it and owning the final product, my opinions have changed. The overall gameplay can be fun, but the cartoony graphics and such get old really fast. Also with the now over-use of the pyro it tends to ruin your game experience rather quickly. The controls are responsive as they should be, the sound and graphics are also on par. If anything the taunts are hysterical and are varried by character, and each character has about 2-3 taunts. Nothing like going Demo and flashing your smilie face at the bad guys just before you spawn. But at the same time, there is nothing to keep the opposing force (little HalfLife reference there) from loading up the gates with motion mines and such, so that they only real way you can get out is by killing yourselves to clear the way for your other team members.
Overall, I'm not too sure this was worth getting, it's fun but then it gets lame and it's just the same old same old thing after awhile. While sporting interesting characters and several maps to choose from, it's just not enough to keep you coming back for more. The Orange Box was a good deal in itself, but TF2 really leaves you feeling like you were left out of the crowd.
