The early beginnings of the show were definitely slow going, but they served their purpose really well. Which was to develop the characters and at least give you a reason to be invested with them.
The whole Steven Bomb however really got a lot of people into the show now- me included and I've taken the time to marathon watch the previous episodes so I have full context on everything.
As for the crossover epsisode, I for one am excited for it. I know it's going to be stupid funny. I'll only be disappointed if the tumblr fandom doesn't meme the fuck out of it for days.
Honestly I just want to see more Jasper. She is best gem.
