Well, one must be careful when using "the". "The" is specific: it tells us that the noun is already known and familiar, or at least very obvious.
I initially misread your example sentence as "candles", but I'll still use "candles" as my example, because "candy" is uncountable and using "candies" would just confuse you more.
I like candles = general meaning.
I like the candles = a specific set of candles. Maybe the ones in a room design or on a cake. The listener would already know which group of candles you mean.
I'm watching TV = viewing in general.
I'm watching the TV = a specific television.
PS. In English, the "I" (io) is always a capital letter.
