I've purposely stayed away, until I could catch up on all the episodes, including the two hour finale I watched last night...
You've all taken this apart already, but this being an audio-video forum, I'll second the notion that tv budget limitations hurt the potential for an epic finale.
CGI - yes, what could we expect? Welling in a suit made for him? 30 lbs in 10 years? Busy working every day as a producer this last season, that exercise wasn't a realistic option to undo 10 years.
Action / fight scenes - No real physical battle with Darkseid. Doomsday got more play. Battle with Zod was pretty awesome. But the lead up to the finale? The best fight / action scenes were between Oliver and Clark!
Writing - ok, there were plot holes to fill over 10 years. Some of them were done well, some of them were hastily written and poof - loose end tied up. Should've done more justice to some characters, but... oh well. Agreed, there was too much time spent on the pre-wedding / wedding scenes. We get that Lois and Clark's relationship is SOLID - no need for pre-wedding jitters to waste 20+ minutes of a 80 min dual episode. Lex and Clark talk to each other - that's it? Some good lines, but overall, I was hoping for more. Maybe Rosenbaum's out of practice in this role, but probably a writer's issue. He wasn't into it enough for me.
Music - OK, iconic William's theme at the end. I'm good with that. The earlier comments about how the music takes us back to 1978, goosebumps, everything - yes, I agree. But what the hell was the 10 year flashback all about? I'll insist that all of you re-play this finale, and actually listen to the music during that flashback. We're audiophiles, and they pull this synthesized "orchestral music" on us for a series finale??? It would've been less CHEESY if they had contracted a real orchestra to play the music. You know - violins, violas, violas, string bass, trumpets...
It looked and sounded exactly like what it was: TV sci-fi. Remember the Superboy series? The soundtrack drove me NUTS. Cheese, cheese, cheese. The finale's use of synthesized string instruments really killed the finale for me - truly disappointing!
I'm of the mind to re-watch that scene, turn off the sound, and ipod the real John William's score. After last night, I wanna watch Superman Returns again, just for the music!!
Thanks for letting me rant about my favorite television show for the last 10 years.
