I totally agree, I think Foundation is a fun book, it just does not deserve the accolades it receives. Same thing with Heinlein, can be kinda fun, but an alien sex cult with the leader hovering naked women into his lap is not that interesting. I just read Ubik and you can see some of these amazing time travel sci-fi concepts playing out, conversely in Heinlein's 'Time Enough For Love' the protagonist goes back in time, sleeps with his own mom, and tells her he is her son from the future. It just feels dumb to me.
