Perhaps you're just not a fan of Deadpool and his wackyness. That's not a slight btw just an observation as not everything is suited for everyones tastes.
That's something i've found odd about fandom and movies in recent years. We all have our favourite characters and teams yet when movies come along it's like we're expected to watch them all just because they're being made.
I have little interest in Suicide Squad or Ant-Man or Avengers which is why i dont bother with them. I might watch them if theyre on TV but i generally stick to movies about comic characters i like and have a history with. I grew up with X-Men, Spider-Man, Batman & Superman, and got into comics with Punisher, Iron Fist, Hulk, Guardians, Nova and some others.
I think with the rise of the MCU and now the DCEU one is expected to watch all just because they're connected. It's a brillint marketing strategy to get people involved but surely some of the time people are only seeing them because they're connected to others and not out of genuine interest in the story and characters.
