No. e4 is not dull.
Is e2e4 dull?

No one first move for White is dull. Dull depends on the opening played, which is determined by both players, not just White's first move.
1.e4 can lead to a very sharp game, a very dull game, or anywhere in between. Nowhere near sufficient information to determine.

Chess is dull. I recommend Hungry Hungry Hippos.
LOL! I can beat that. How about Twister, or better yet, Strip Twister! Works like Strip Poker!

No.. it is good..
Not as good as 1. f3, but close.
? f3 Why? It doesnt open lines for any officer but open line black Queen to make mate or chess from h 4. Are you kidding?

It leads to sharp opening, where the whole board could be open to attacks. Rapid development is paramount, and often bishops are better than knights.

I always start with e2e4. I'm afraid to try nothing else. But I feel it is dull. My level of players seems other too start with e2e4. I'm little bored.
1. e4 develops the Qd1 and Bf1, occupies the center, and enables rapid castling on the side safest for the king.
Do you have a move that does more than this?
No. I didn't say it is a bad move. I just feel very bored because I allways start e4. I feel like I'm a robot.

Try opening with different moves then.
A favorite of 'Swedish' GM "Ulf Anderson" as 'white' when confronted with that, opening 2 move 'symetrical'.. was to go into a voluntary 'half-tempo' disadvantage - In the hopes of throwing his opponent a metaphorical 'curve ball'/'Vienna' game.. with, '2. Nc3' - Likely, to be followed, with '3. g3' {!?}
