It's kind of embarrassing, but I was like that with Enterprise I got bored and stopped watching and then just after the show was over I found out that at the end they started pulling out all this crazy stuff: let's have adventures on Vulcan! Now we're in the mirror universe! Here are some generically-engineered humans like Kahn! etc. These episodes weren't so much really good as they were entertainingly cracky, but I put a lot of effort into catching up with re-runs, which involved setting the VCR because they were on at maybe 3:00 am or something where I lived.
