Love and the Hulk are quite a rare combination in a story, and this episode is a welcome addition to that genre. There's some nice foreshadowing of the Hulk's brief love life at the beginning when Betty is asking Bruce what went wrong between them. I did find it overly simplistic that Talbot found out about the Time Projector simply by eavesdropping on Rick's conversation, and that neither Rick nor Bruce seem to mind about it. It would have been better to state that the military would have sources to provide such information. Bruce's idea to alter history to prevent him from becoming the Hulk is an interesting one, but there are obvious paradox problems (which are admittedly beyond the scope of a half-hour cartoon!). Having Rita just happen to be poisoned just as everyone has left for NYC is unfortunately far too obvious of a plot device. The Hulk's instant romance is as fairly plausible as they go in shows like this, but Umela's jealous boyfriend is a very ineffective adversary. The prehistoric world made for a good change of locale, but naturally it has both humans and dinosaurs impossibly living together (perhaps this was meant to be the Savage Land?).  Although their relationship was brief, the Hulk shedding tears at being unable to remain with Umela is quite a touching moment, as is Bruce's almost-memory of having lost here.

 
Heh.  This was written before it was common knowledge that humans and Dinosaurs did not exist in the same time.  (Many movies and tv shows of the time made the same error.)  I'm not going to hold that against this episode.  This was really fun despite it's glaring flaws.  Time machine stories are always fun to me, no matter who is involved.  The icing on the cake was having Hulk develop a love interest.  And you're right Jon, the ending was a touching moment.  Who'd have thought that the Hulk could find happiness?  The sub plot with Rita was unnecessary but it was downright humorous that Betty, General Ross and Talbot didn't realize that Banner is the Hulk.  They travel to New York with Banner and, as soon as Banner leaves the room, the Hulk shows up. Of all the places in the world, the Hulk is in the same building in New York with the supporting characters. If I were them I would be quite curious at that point.  The whole room is transported to prehistoric times with the Hulk, then Banner shows up in prehistoric times!  He wasn't even in the room to the cast's knowledge!  Wow.  It was also quite shocking how easily Banner turned into the Hulk at the beginning of the episode;  he was having trouble finding Rick in another room.  Geez, if Banner's condition is that bad, I wouldn't think he could even make it to the shower every morning before the Hulk came out.  Since I hadn't watched this show since I was a young teen, I'd never realized how many episode used old movie plots as their basis.  (This episode, "The Cyclops project", "The Incredible Shrinking Hulk".)  You'd think the writers would prefer to use old Hulk comic book plots instead.
